Jason Lowe commented on YARN-3942:
----------------------------------
To setup for the Tez UI,
yarn.timeline-service.entity-file-store.summary-entity-types needs to be set to
something like YARN_APPLICATION,TEZ_DAG_ID,TEZ_APPLICATION. That directs the
store plugin to copy those entity types to the main leveldb database that the
cluster overview page (i.e.: the main "All DAGs" page) references. This allows
the main TezUI page to remain functional without requiring a query on every
application file. All other entity types will be served from the HDFS entity
files created by the job.

> 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.
