[jira] [Commented] (YARN-2010) RM can't transition to active if it can't recover an app attempt

["Rohith (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-2010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13987590#comment-13987590 ] 

Rohith commented on YARN-2010:
------------------------------

For completed applications before starting in secured mode, clientTokenMaterKey is null. After starting in secured mode, recovery of apps fails since clientTokenMasterKey is null. During recovering application, rm should have intellegence to decide whether recovering applicaiton has run in secured mode or non secured mode. This is possible by checking cilentTokenMasterKey for null.

> 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.
