Vrushali C commented on YARN-7714:
----------------------------------
Hmm, there isn't a timeline server in atsv2 but it exists in 1 and 1.5, perhaps
this option is used for those versions? Also, in 1/1.5, there isn't a separate
reader I think.
So, I think it's
ATSv1 and ATSv1.5 => timeline server
ATSv2 => timeline reader
What do you think?

> Key: YARN-7714
> URL: https://issues.apache.org/jira/browse/YARN-7714
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelinereader
> Affects Versions: 3.0.0
> Reporter: Haibo Chen
> Assignee: Haibo Chen
>
> From hadoop-yarn-project/hadoop-yarn/conf/yarn-env.sh,
> {code}
> # 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=
> {code}
> However, YARN_TIMELINESERVER_OPTS does not work. The correct one to set is
> YARN_TIMELINEREADER_OPTS instead.
