Rohith commented on YARN-3410: ------------------------------ [~leftnoteasy] IIUC, this is an Improvement on admin service. I have changed to Improvement. If you still think it is a Bug, let handle as Bug. > YARN admin should be able to remove individual application records from > RMStateStore > ------------------------------------------------------------------------------------ > > Key: YARN-3410 > URL: https://issues.apache.org/jira/browse/YARN-3410 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager, yarn > Reporter: Wangda Tan > Assignee: Rohith > Priority: Critical > > When RM state store entered an unexpected state, one example is YARN-2340, > when an attempt is not in final state but app already completed, RM can never > get up unless format RMStateStore. > I think we should support remove individual application records from > RMStateStore to unblock RM admin make choice of either waiting for a fix or > format state store. > In addition, RM should be able to report all fatal errors (which will > shutdown RM) when doing app recovery, this can save admin some time to remove > apps in bad state. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
