             Summary: Remove the logic to inject entity owner as the primary 
                 Key: YARN-2818
                 URL: https://issues.apache.org/jira/browse/YARN-2818
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver
            Reporter: Zhijie Shen
            Assignee: Zhijie Shen
            Priority: Critical

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).
