Karthik Kambatla created YARN-2268:
--------------------------------------
Summary: Disallow formatting the RMStateStore when there is an RM
running
Key: YARN-2268
URL: https://issues.apache.org/jira/browse/YARN-2268
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.6.0
Reporter: Karthik Kambatla
YARN-2131 adds a way to format the RMStateStore. However, it can be a problem
if we format the store while an RM is actively using it. It would be nice to
fail the format if there is an RM running and using this store.
