> 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).
