[jira] [Commented] (MAPREDUCE-4830) Restore JT DelegationTokenSecretManager state on restart

Posted by "Tom White (JIRA)" <ji...@apache.org>.
    [ https://issues.apache.org/jira/browse/MAPREDUCE-4830?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13506570#comment-13506570 ] 

Tom White commented on MAPREDUCE-4830:
--------------------------------------

In addition to DelegationTokenSecretManager's state not being restored, there's a problem with delegation token renewal for JT tokens. When jobs are recovered delegation tokens are renewed immediately (see DelegationTokenRenewal.registerDelegationTokensForRenewal), and this happens before the JT RPC server has started, so the renewal will fail and the delegation token will be removed. This will cause the job to fail.
