Jason Lowe commented on TEZ-2628:
---------------------------------
Yes, sorry this wasn't clear. The group of the the timeline server active
directory needs to be hadoop (or a similar restricted group for the admin
daemons) so child directories inherit this group. The timeline server needs
read access to the files, but we don't want it opened up to everyone. It is
similar to how the done_intermediate directory is setup for MapReduce history.

> This provides another history logging alternative that conceptually the same
> as the timeline logging service but logs the entities to a file rather than
> posting the events to the timeline server directly. When coupled with the
> timeline store plugin from YARN-3942 it allows the Tez job to be decoupled
> from the timeline server yet the Tez UI can still function properly.
