Hitesh Shah commented on YARN-3942:
-----------------------------------

Thanks [~gss2002]. One point to note - if you use long running Hive sessions, 
this will cause an OOM in the timeline server as the data is cached on a per 
"session" basis. I am not sure if there is another simple way to disable Hive 
session re-use in the HiveServer \cc [~vikram.dixit]

> This adds a new timeline store plugin that is intended as a stop-gap measure 
> to mitigate some of the issues we've seen with ATS v1 while waiting for ATS 
> v2.  The intent of this plugin is to provide a workable solution for running 
> the Tez UI against the timeline server on a large-scale clusters running many 
> thousands of jobs per day.
