Description

From hadoop-yarn-project/hadoop-yarn/conf/yarn-env.sh,

# Specify the max heapsize for the timelineserver.  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_TIMELINESERVER_OPTS.
# Default is the same as HADOOP_HEAPSIZE_MAX.
#export YARN_TIMELINE_HEAPSIZE=

# Specify the JVM options to be used when starting the TimeLineServer.
# These options will be appended to the options specified as HADOOP_OPTS
# and therefore may override any similar flags set in HADOOP_OPTS
#
# See ResourceManager for some examples
#
#export YARN_TIMELINESERVER_OPTS=

However, YARN_TIMELINESERVER_OPTS does not work. The correct one to set is YARN_TIMELINEREADER_OPTS instead.
