Zhijie Shen commented on YARN-3942:
-----------------------------------
Thanks for this work. Agree it's a good interim step between v1 and v2. I have
a first scan of this patch, and am fine with the idea overall. As far as I can
tell, the unsupported case is to get entities of the same type across
applications. Other than that, the HDFS data path seems to work fine. [~jlowe],
if you'd like to elaborate the drawback a bit, it will be helpful.
Will continue to review the patch, and post more detailed comments.

> 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.
