---------------------------------
Summary: Remove the logic to inject entity owner as the primary
filter
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).
