+Yarn Scheduler Load Simulator (SLS)
+
+SLS is a stress and performance harness for the Yarn Resource Manager Scheduler
+that exercises the scheduler implementation simulating the cluster size and the
+applications load without having to have a cluster nor applications.
+
+SLS runs a regular RM without RPC endpoints and uses a NodeManager and
+Application Manager simulators to send and receive events simulating cluster
+and application load behavior.
+
+The size of the cluster and the application load is scripted in a configuration
+file.

+* Overview
+
+** Overview
+
+  The Yarn scheduler is a fertile area of interest with different
+  implementations, e.g., Fifo, Capacity and Fair schedulers. Meanwhile, several
+  optimizations are also made to improve scheduler performance for different
+  scenarios and workload. Each scheduler algorithm has its own set of features,
+  and drives scheduling decisions by many factors, such as fairness, capacity
+  guarantee, resource availability, etc. It is very important to evaluate a
+  scheduler algorithm very well before we deploy in a production cluster.
+  Unfortunately, currently it is non-trivial to evaluate a scheduler algorithm.
+  Evaluating in a real cluster is always time and cost consuming, and it is
+  also very hard to find a large-enough cluster. Hence, a simulator which can
+  predict how well a scheduler algorithm for some specific workload would be
+  quite useful.
+
+  The Yarn Scheduler Load Simulator (SLS) is such a tool, which can simulate
+  large-scale Yarn clusters and application loads in a single machine.This
+  simulator would be invaluable in furthering Yarn by providing a tool for
+  researchers and developers to prototype new scheduler features and predict
+  their behavior and performance with reasonable amount of confidence,
+  thereby aiding rapid innovation.
+
+  The simulator will exercise the real Yarn <<<ResourceManager>>> removing the
+  network factor by simulating <<<NodeManagers>>> and <<<ApplicationMasters>>>
+  via handling and dispatching <<<NM>>>/<<<AMs>>> heartbeat events from within
+  the same JVM. To keep tracking of scheduler behavior and performance, a
+  scheduler wrapper will wrap the real scheduler.
+
+  The size of the cluster and the application load can be loaded from
+  configuration files, which are generated from job history files directly by
+  adopting {{{https://hadoop.apache.org/docs/stable/rumen.html}Apache Rumen}}.
+
+  The simulator will produce real time metrics while executing, including:
+
+  * Resource usages for whole cluster and each queue, which can be utilized to
+    configure cluster and queue's capacity.
+
+  * The detailed application execution trace (recorded in relation to simulated
+    time), which can be analyzed to understand/validate the scheduler behavior
+    (individual jobs turn around time, throughput, fairness, capacity guarantee,
+    etc.).
+
+  * Several key metrics of scheduler algorithm, such as time cost of each
+    scheduler operation (allocate, handle, etc.), which can be utilized by Hadoop
+    developers to find the code spots and scalability limits.
+
+** Goals
+
+  * Exercise the scheduler at scale without a real cluster using real job
+    traces.
+
+  * Being able to simulate real workloads.
+
+** Architecture
+
+  The following figure illustrates the implementation architecture of the
+  simulator.
+
+[images/sls_arch.png] The architecture of the simulator
+
+  The simulator takes input of workload traces, and fetches the cluster and
+  applications information. For each NM and AM, the simulator builds a simulator
+  to simulate their running. All NM/AM simulators run in a thread pool. The
+  simulator reuses Yarn Resource Manager, and builds a wrapper out of the
+  scheduler. The Scheduler Wrapper can track the scheduler behaviors and
+  generates several logs, which are the outputs of the simulator and can be
+  further analyzed.
+
+** Usecases
+
+  * Engineering
+
+    * Verify correctness of scheduler algorithm under load
+
+    * Cheap/practical way for finding code hotspots/critical-path.
+
+    * Validate the impact of changes and new features.
+
+    * Determine what drives the scheduler scalability limits.
+
+      []
+
+  * QA
+
+    * Validate scheduler behavior for "large" clusters and several workload
+    profiles.
+
+  * Solutions/Sales.
+
+    * Sizing model for predefined/typical workloads.
+
+    * Cluster sizing tool using real customer data (job traces).
+
+    * Determine minimum SLAs under a particular workload.
+
+* Usage
+
+  This section will show how to use the simulator. Here let <<<$HADOOP_ROOT>>>
+  represent the Hadoop install directory. If you build Hadoop yourself,
+  <<<$HADOOP_ROOT>>> is <<<hadoop-dist/target/hadoop-$VERSION>>>. The simulator
+  is located at <<<$HADOOP_ROOT/share/hadoop/tools/sls>>>. The fold <<<sls>>>
+  containers four directories: <<<bin>>>, <<<html>>>, <<<sample-conf>>>, and
+  <<<sample-data>>>
+
+  * <<<bin>>>: contains running scripts for the simulator.
+
+  * <<<html>>>: contains several html/css/js files we needed for real-time
+  tracking.
+
+  * <<<sample-conf>>>: specifies the simulator configurations.
+
+  * <<<sample-data>>>: provides an example rumen trace, which can be used to
+  generate inputs of the simulator.
+
+    []
+
+  The following sections will describe how to use the simulator step by step.
+  Before start, make sure that command <<<hadoop>>> is included in your
+  <<<$PATH>>> environment parameter.
+
+** Step 1: Configure Hadoop and the simulator
+
+  Before we start, make sure Hadoop and the simulator are configured well.
+  All configuration files for Hadoop and the simulator should be placed in
+  directory <<<$HADOOP_ROOT/etc/hadoop>>>, where the <<<ResourceManager>>>
+  and Yarn scheduler load their configurations. Directory
+  <<<$HADOOP_ROOT/share/hadoop/tools/sls/sample-conf/>>> provides several
+  example configurations, that can be used to start a demo.
+
+  For configuration of Hadoop and Yarn scheduler, users can refer to Yarn’s
+  website ({{{http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/}
+  http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/}}).
+
+  For the simulator, it loads configuration information from file
+  <<<$HADOOP_ROOT/etc/hadoop/sls-runner.xml>>>.
+
+  Here we illustrate each configuration parameter in <<<sls-runner.xml>>>.
+  Note that <<<$HADOOP_ROOT/share/hadoop/tools/sls/sample-conf/sls-runner.xml>>>
+  contains all the default values for these configuration parameters.
+
+  * <<<yarn.sls.runner.pool.size>>>
+
+  The simulator uses a thread pool to simulate the <<<NM>>> and <<<AM>>> running
+  , and this parameter specifies the number of threads in the pool.
+
+  * <<<yarn.sls.nm.memory.mb>>>
+
+  The total memory for each <<<NMSimulator>>>.
+
+  * <<<yarn.sls.nm.vcores>>>
+
+  The total vCores for each <<<NMSimulator>>>.
+
+  * <<<yarn.sls.nm.heartbeat.interval.ms>>>
+
+  The heartbeat interval for each <<<NMSimulator>>>.
+
+  * <<<yarn.sls.am.heartbeat.interval.ms>>>
+
+  The heartbeat interval for each <<<AMSimulator>>>.
+
+  * <<<yarn.sls.am.type.mapreduce>>>
+
+  The <<<AMSimulator>>> implementation for MapReduce-like applications.
+  Users can specify implementations for other type of applications.
+
+  * <<<yarn.sls.container.memory.mb>>>
+
+  The memory required for each container simulator.
+
+  * <<<yarn.sls.container.vcores>>>
+
+  The vCores required for each container simulator.
+
+  * <<<yarn.sls.runner.metrics.switch>>>
+
+  The simulator introduces {{{http://metrics.codahale.com/}Metrics}} to measure
+  the behaviors of critical components and operations. This field specifies
+  whether we open (<<<ON>>>) or close (<<<OFF>>>) the Metrics running.
+
+  * <<<yarn.sls.metrics.web.address.port>>>
+
+  The port used by simulator to provide real-time tracking. The default value is
+  10001.
+
+  * <<<org.apache.hadoop.yarn.server.resourcemanager.scheduler.fifo.FifoScheduler>>>
+
+  The implementation of scheduler metrics of Fifo Scheduler.
+
+  * <<<org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler>>>
+
+  The implementation of scheduler metrics of Fair Scheduler.
+
+  * <<<org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler>>>
+
+  The implementation of scheduler metrics of Capacity Scheduler.
+
+** Step 2: Run the simulator
+
+  The simulator supports two types of input files: the rumen traces and its own
+  input traces. The script to start the simulator is <<<slsrun.sh>>>.
+
++----+
+$ $HADOOP_ROOT/share/hadoop/tools/sls/bin/slsrun.sh
+    --input-rumen|--input-sls=<TRACE_FILE1,TRACE_FILE2,...>
+    --output-dir=<SLS_SIMULATION_OUTPUT_DIRECTORY> [--nodes=<SLS_NODES_FILE>]
+    [--track-jobs=<JOBID1,JOBID2,...>] [--print-simulation]
++----+
+
+  * <<<--input-rumen>>>: The input rumen trace files. Users can input multiple
+  files, separated by comma. One example trace is provided in
+  <<<$HADOOP_ROOT/share/hadoop/tools/sls/sample-data/2jobs2min-rumen-jh.json>>>.
+
+  * <<<--input-sls>>>: Simulator its own file format. The simulator also
+  provides a tool to convert rumen traces to sls traces (<<<rumen2sls.sh>>>).
+  Refer to appendix for an example of sls input json file.
+
+  * <<<--output-dir>>>: The output directory for generated running logs and
+  metrics.
+
+  * <<<--nodes>>>: The cluster topology. By default, the simulator will use the
+  topology fetched from the input json files. Users can specifies a new topology
+  by setting this parameter. Refer to the appendix for the topology file format.
+
+  * <<<--track-jobs>>>: The particular jobs that will be tracked during
+  simulator running, spearated by comma.
+
+  * <<<--print-simulation>>>: Whether to print out simulation information
+  before simulator running, including number of nodes, applications, tasks,
+  and information for each application.
+
+  In comparison to rumen format, here the sls format is much simpler and users
+  can easily generate various workload. The simulator also provides a tool to
+  convert rumen traces to sls traces.
+
++----+
+$ $HADOOP_ROOT/share/hadoop/tools/sls/bin/rumen2sls.sh
+    --rumen-file=<RUMEN_FILE>
+    --output-dir=<SLS_OUTPUT_DIRECTORY>
+    [--output-prefix=<SLS_FILE_PREFIX>]
++----+
+
+  * <<<--rumen-file>>>: The rumen format file. One example trace is provided
+  in directory <<<sample-data>>>.
+
+  * <<<--output-dir>>>: The output directory of generated simulation traces.
+  Two files will be generated in this output directory, including one trace
+  file including all job and task information, and another file showing the
+  topology information.
+
+  * <<<--output-prefix>>>: The prefix of the generated files. The default value
+  is ”sls”, and the two generated files are <<<sls-jobs.json>>> and
+  <<<sls-nodes.json>>>.
+
+* Metrics
+
+  The Yarn Scheduler Load Simulator has integrated
+  {{{http://metrics.codahale.com/}Metrics}} to measure the behaviors of critical
+  components and operations, including running applications and containers,
+  cluster available resources, scheduler operation timecost, et al. If the
+  switch <<<yarn.sls.runner.metrics.switch>>> is set <<<ON>>>, <<<Metrics>>>
+  will run and output it logs in <<<--output-dir>>> directory specified by users.
+  Users can track these information during simulator running, and can also
+  analyze these logs after running to evaluate the scheduler performance.
+
+** Real-time Tracking
+
+  The simulator provides an interface for tracking its running in real-time.
+  Users can go to <<<http://host:port/simulate>>> to track whole running,
+  and <<<http://host:port/track>>> to track a particular job or queue. Here
+  the <<<host>>> is the place when we run the simulator, and <<<port>>> is
+  the value configured by <<<yarn.sls.metrics.web.address.port>>> (default value
+  is 10001).
+
+  Here we'll illustrate each chart shown in the webpage.
+
+  The first figure describes the number of running applications and containers.
+
+[images/sls_running_apps_containers.png] Number of running applications/containers
+
+  The second figure describes the allocated and available resources (memory)
+  in the cluster.
+
+[images/sls_cluster_memory.png] Cluster Resource (Memory)
+
+  The third figure describes the allocated resource for each queue. Here we have
+  three queues: sls_queue_1, sls_queue_2, and sls_queue_3.The first two queues
+  are configured with 25% share, while the last one has 50% share.
+
+[images/sls_queue_allocated_memory.png] Queue Allocated Resource (Memory)
+
+  The fourth figure describes the timecost for each scheduler operation.
+
+[images/sls_scheduler_operation_timecost.png] Scheduler Opertion Timecost
+
+  Finally, we measure the memory used by the simulator.
+
+[images/sls_JVM.png] JVM Memory
+
+  The simulator also provides an interface for tracking some particular
+  jobs and queues. Go to <<<http://<Host>:<Port>/track>>> to get these
+  information.
+
+  Here the first figure illustrates the resource usage information for queue
+  <<<SLS_Queue_1>>>.
+
+[images/sls_track_queue.png] Tracking Queue <<<sls_queue_3>>>
+
+  The second figure illustrates the resource usage information for job
+  <<<job_1369942127770_0653>>>.
+
+[images/sls_track_job.png] Tracking Job <<<job_1369942127770_0653>>>
+
+** Offline Analysis
+
+  After the simulator finishes, all logs are saved in the output directory
+  specified by <<<--output-dir>>> in
+  <<<$HADOOP_ROOT/share/hadoop/tools/sls/bin/slsrun.sh>>>.
+
+  * File <<<realtimetrack.json>>>: records all real-time tracking logs every 1
+  second.
+
+  * File <<<jobruntime.csv>>>: records all jobs’ start and end time in the
+  simulator.
+
+  * Folder <<<metrics>>>: logs generated by the Metrics.
+
+    []
+
+  Users can also reproduce those real-time tracking charts in offline mode.
+  Just upload the <<<realtimetrack.json>>> to
+  <<<$HADOOP_ROOT/share/hadoop/tools/sls/html/showSimulationTrace.html>>>.
+  For browser security problem, need to put files <<<realtimetrack.json>>> and
+  <<<showSimulationTrace.html>>> in the same directory.
