Description

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:

export YARN_HISTORYSERVER_HEAPSIZE={{apptimelineserver_heapsize}}

should be replaced with:

export YARN_TIMELINESERVER_HEAPSIZE={{apptimelineserver_heapsize}}
