------------------------------

FAILURE: Integrated in Hadoop-Yarn-trunk #736 (See 
[https://builds.apache.org/job/Hadoop-Yarn-trunk/736/])
YARN-2818. Removed the now unnecessary user entity injection from Timeline 
service given we now have domains. Contributed by Zhijie Shen. (vinodkv: rev 
f5b19bed7d71979dc8685b03152188902b6e45e9)

> In 2.5, we inject owner info as a primary filter to support entity-level 
> acls. Since 2.6, we have a different acls solution (YARN-2102). Therefore, 
> there's no need to inject owner info. There're two motivations:
> 1. For leveldb timeline store, the primary filter is expensive. When we have 
> a primary filter, we need to make a complete copy of the entity on the logic 
> index table.
> 2. Owner info is incomplete. Say we want to put E1 (owner = "tester", 
> relatedEntity = "E2"). If E2 doesn't exist before, leveldb timeline store 
> will create an empty E2 without owner info (at the db point of view, it 
> doesn't know owner is a "special" primary filter).
