Zhijie Shen created YARN-3399:
---------------------------------
Summary: Default cluster ID for RM HA
Key: YARN-3399
URL: https://issues.apache.org/jira/browse/YARN-3399
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Reporter: Zhijie Shen
In YARN-3040, timeline service will set the default cluster ID if users don't
provide one. RM HA's current behavior is a bit different when users don't
provide cluster ID. IllegalArgumentException will throw instead. Let's continue
the discussion if RM HA needs the default cluster ID or not here, and what's
the proper default cluster ID.
