- ## THIS FILE ACTS AS AN OVERRIDE FOR hadoop-env.sh FOR ALL
- ## WORK DONE BY THE yarn AND RELATED COMMANDS.

- ## Precedence rules:
- ##
- ## yarn-env.sh > hadoop-env.sh > hard-coded defaults
- ##
- ## YARN_xyz > HADOOP_xyz > hard-coded defaults
- ##
- ###
- # Resource Manager specific parameters
- ###
- # Specify the max heapsize for the ResourceManager. If no units are
- # given, it will be assumed to be in MB.
- # This value will be overridden by an Xmx setting specified in either
- # HADOOP_OPTS and/or YARN_RESOURCEMANAGER_OPTS.
- # Default is the same as HADOOP_HEAPSIZE_MAX
- #export YARN_RESOURCEMANAGER_HEAPSIZE=
- # Specify the JVM options to be used when starting the ResourceManager.
- # These options will be appended to the options specified as HADOOP_OPTS
- # and therefore may override any similar flags set in HADOOP_OPTS
- #
- # Examples for a Sun/Oracle JDK:
- # a) override the appsummary log file:
- # export YARN_RESOURCEMANAGER_OPTS="-Dyarn.server.resourcemanager.appsummary.log.file=rm-appsummary.log -Dyarn.server.resourcemanager.appsummary.logger=INFO,RMSUMMARY"
- #
- # b) Set JMX options
- # export YARN_RESOURCEMANAGER_OPTS="-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=1026"
- #
- # c) Set garbage collection logs from hadoop-env.sh
- # export YARN_RESOURCE_MANAGER_OPTS="${HADOOP_GC_SETTINGS} -Xloggc:${HADOOP_LOG_DIR}/gc-rm.log-$(date +'%Y%m%d%H%M')"
- #
- # d) ... or set them directly
