|
|
|
+ <b>Add support whitelist for system users to Yarn container-executor.c</b><br>
|
|
|
+ <blockquote>Currently container-executor.c has a banned set of users (mapred, hdfs & bin) and configurable min.user.id (defaulting to 1000).
|
|
|
+
|
|
|
+This presents a problem for systems that run as system users (below 1000) if these systems want to start containers.
|
|
|
+
|
|
|
+Systems like Impala fit in this category. A (local) 'impala' system user is created when installing Impala on the nodes.
|
|
|
+
|
|
|
+Note that the same thing happens when installing system like HDFS, Yarn, Oozie, from packages (Bigtop); local system users are created.
|
|
|
+
|
|
|
+For Impala to be able to run containers in a secure cluster, the 'impala' system user must whitelisted.
|
|
|
+
|
|
|
+For this, adding a configuration 'allowed.system.users' option in the container-executor.cfg and the logic in container-executor.c would allow the usernames in that list.
|
|
|
+
|
|
|
+Because system users are not guaranteed to have the same UID in different machines, the 'allowed.system.users' property should use usernames and not UIDs.

+ <b>Make ApplicationConstants.Environment.USER definition OS neutral</b><br>
|
|
|
+ <blockquote>In YARN-557, we added some code to make {{ApplicationConstants.Environment.USER}} has OS-specific definition in order to fix the unit test TestUnmanagedAMLauncher. In YARN-571, the relevant test code was corrected. In YARN-602, we actually will explicitly set the environment variables for the child containers. With these changes, I think we can revert the YARN-557 change to make {{ApplicationConstants.Environment.USER}} OS neutral. The main benefit is that we can use the same method over the Enum constants. This should also fix the TestContainerLaunch#testContainerEnvVariables failure on Windows. </blockquote></li>

|
+ <b>Improve help message for $ yarn logs</b><br>
|
|
|
+ <blockquote>There are 2 parts I am proposing in this jira. They can be fixed together in one patch.
|
|
|
+
|
|
|
+1. Standardize help message for required parameter of $ yarn logs
|
|
|
+YARN CLI has a command "logs" ($ yarn logs). The command always requires a parameter of "-applicationId <arg>". However, help message of the command does not make it clear. It lists -applicationId as optional parameter. If I don't set it, YARN CLI will complain this is missing. It is better to use standard required notation used in other Linux command for help message. Any user familiar to the command can understand that this parameter is needed more easily.

|
|
+ <b>TestContainerLaunch fails on Windows</b><br>
|
|
|
+ <blockquote>Several cases in this unit tests fail on Windows. (Append error log at the end.)
|
|
|
+
|
|
|
+testInvalidEnvSyntaxDiagnostics fails because the difference between cmd and bash script error handling. If some command fails in the cmd script, cmd will continue execute the the rest of the script command. Error handling needs to be explicitly carried out in the script file. The error code of the last command will be returned as the error code of the whole script. In this test, some error happened in the middle of the cmd script, the test expect an exception and non-zero error code. In the cmd script, the intermediate errors are ignored. The last command "call" succeeded and there is no exception.
|
|
|
+
|
|
|
+testContainerLaunchStdoutAndStderrDiagnostics fails due to wrong cmd commands used by the test.
|
|
|
+
|
|
|
+testContainerEnvVariables and testDelayedKill fail due to a regression from YARN-906.

+ <b>Capacity Scheduler tries to reserve the memory more than what node manager reports.</b><br>
|
|
|
+ <blockquote>I have 2 node managers.
|
|
|
+* one with 1024 MB memory.(nm1)
|
|
|
+* second with 2048 MB memory.(nm2)
|
|
|
+I am submitting simple map reduce application with 1 mapper and one reducer with 1024mb each. The steps to reproduce this are
|
|
|
+* stop nm2 with 2048MB memory.( This I am doing to make sure that this node's heartbeat doesn't reach RM first).
|
|
|
+* now submit application. As soon as it receives first node's (nm1) heartbeat it will try to reserve memory for AM-container (2048MB). However it has only 1024MB of memory.
|
|
|
+* now start nm2 with 2048 MB memory.
|
|
|
+
|
|
|
+It hangs forever... Ideally this has two potential issues.
|
|
|
+* It should not try to reserve memory on a node manager which is never going to give requested memory. i.e. Current max capability of node manager is 1024MB but 2048MB is reserved on it. But it still does that.
|
|
|
+* Say 2048MB is reserved on nm1 but nm2 comes back with 2048MB available memory. In this case if the original request was made without any locality then scheduler should unreserve memory on nm1 and allocate requested 2048MB container on nm2.
