| # Generic settings for YARN |
| ### |
| |
| # User for YARN daemons |
| export HADOOP_YARN_USER=${HADOOP_YARN_USER:-yarn} |
| |
| # |
| # By default, YARN will use HADOOP_CONF_DIR. Specify a custom |
| # YARN_CONF_DIR here |
| # export YARN_CONF_DIR="${YARN_CONF_DIR:-$HADOOP_YARN_HOME/conf}" |
| # |
| |
| # Override Hadoop's log directory & file |
| # export YARN_LOG_DIR="$HADOOP_YARN_HOME/logs" |
| # export YARN_LOGFILE='yarn.log' |
| |
| # Need a custom-to-YARN service-level authorization policy file? |
| # export YARN_POLICYFILE="yarn-policy.xml" |
| |
| #Override the log4j settings for all YARN apps |
| # export YARN_ROOT_LOGGER="INFO,console" |
| |
| ### |
| # Resource Manager specific parameters |
| ### |
| |
| # Specify the max heapsize for the ResourceManager using a numerical value |
| # in the scale of MB. For example, to specify an jvm option of -Xmx1000m, set |
| # the value to 1000. |
| # This value will be overridden by an Xmx setting specified in either YARN_OPTS, |
| # HADOOP_OPTS, and/or YARN_RESOURCEMANAGER_OPTS. |
| # If not specified, the default value will be picked from either YARN_HEAPMAX |
| # or JAVA_HEAP_MAX with YARN_HEAPMAX as the preferred option of the two. |
| # |
| #export YARN_RESOURCEMANAGER_HEAPSIZE=1000 |
| |
| # Specify the JVM options to be used when starting the ResourceManager. |
| # These options will be appended to the options specified as YARN_OPTS |
| # and therefore may override any similar flags set in YARN_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-$(date +'%Y%m%d%H%M')" |
| # |
| # d) ... or set them directly |
| # export YARN_RESOURCEMANAGER_OPTS="-verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -Xloggc:${HADOOP_LOG_DIR}/gc-rm.log-$(date +'%Y%m%d%H%M')" |

| ### |
| # Node Manager specific parameters |
| ### |
| |
| # Specify the max Heapsize for the NodeManager using a numerical value |
| # in the scale of MB. For example, to specify an jvm option of -Xmx1000m, set |
| # the value to 1000. |
| # This value will be overridden by an Xmx setting specified in either YARN_OPTS, |
| # HADOOP_OPTS, and/or YARN_NODEMANAGER_OPTS. |
| # If not specified, the default value will be picked from either YARN_HEAPMAX |
| # or JAVA_HEAP_MAX with YARN_HEAPMAX as the preferred option of the two. |
| # |
| #export YARN_NODEMANAGER_HEAPSIZE=1000 |
| |
| # Specify the JVM options to be used when starting the NodeManager. |
| # These options will be appended to the options specified as YARN_OPTS |
| # and therefore may override any similar flags set in YARN_OPTS |
| # |
| # See ResourceManager for some examples |
| # |
| #export YARN_NODEMANAGER_OPTS= |
| |
| ### |
| # TimeLineServer specifc parameters |
| ### |
| |
| # Specify the max Heapsize for the timeline server using a numerical value |
| # in the scale of MB. For example, to specify an jvm option of -Xmx1000m, set |
| # the value to 1000. |
| # This value will be overridden by an Xmx setting specified in either YARN_OPTS, |
| # HADOOP_OPTS, and/or YARN_TIMELINESERVER_OPTS. |
| # If not specified, the default value will be picked from either YARN_HEAPMAX |
| # or JAVA_HEAP_MAX with YARN_HEAPMAX as the preferred option of the two. |
| # |
| #export YARN_TIMELINESERVER_HEAPSIZE=1000 |
| |
| # Specify the JVM options to be used when starting the TimeLineServer. |
| # These options will be appended to the options specified as YARN_OPTS |
| # and therefore may override any similar flags set in YARN_OPTS |
