[jira] [Commented] (MAPREDUCE-4860) Inconsistent synchronization in
mapreduce.security.token.DelegationTokenRenewal
[ https://issues.apache.org/jira/browse/MAPREDUCE-4860?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13526697#comment-13526697 ]
Karthik Kambatla commented on MAPREDUCE-4860:
---------------------------------------------
In fact, I wonder why we can't use common.DelegationTokenRenewer for token renewal. That avoids duplicating code too.
