Subject [jira] [Commented] (YARN-2010) RM can't transition to active if it can't recover an app attempt
Date Wed, 28 May 2014 06:56:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-2010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14010854#comment-14010854
] 

Karthik Kambatla commented on YARN-2010:
----------------------------------------

bq. In non-workpreserving restart, since the old attempt will be essentially killed on RM
restart, new attempt will be automatically started and it will have the new clientTokenMaterKey
key generated. So we may not need to fail this app.
The stack trace corresponds to non-work-preserving restart. I am not sure I understand the
concern.

This JIRA addresses all cases where an app recovery fails. Examples include token issues,
queue ACL changes that disallow the user from submitting to the queue etc. In any of these
cases, users should have the option of continuing with starting the RM.

> If the RM fails to recover an app attempt, it won't come up. We should make it more resilient.
> Specifically, the underlying error is that the app was submitted before Kerberos security
got turned on. Makes sense for the app to fail in this case. But YARN should still start.
