------------------------------
    Resolution: Not A Problem

>                 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.
