> There's a parameter called "AppTimelineServer Java heap size" under YARN > Configs.
> Changing this does not affect the actual heap size used by AppTimeLineServer.
> No matter what the setting is, 1024MB is always used.
> This is because the yarn-env template has a bug.
> The following line: 
> {code}
> export YARN_HISTORYSERVER_HEAPSIZE={{apptimelineserver_heapsize}}
> {code}
> should be replaced with:
> {code}
> export YARN_TIMELINESERVER_HEAPSIZE={{apptimelineserver_heapsize}}
> {code}
