    [ https://issues.apache.org/jira/browse/HADOOP-9046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13504691#comment-13504691

Ivan A. Veselovsky commented on HADOOP-9046:

Hi, Robert,
looks like I found the reason of delay: the main thread locks for long time when waiting to
enter the synchronized method org.apache.hadoop.fs.DelegationTokenRenewer.removeRenewAction(T),
and this operation is invoked in StateSynchronizer *without* a timeout.   
I will update the patch when i fix this. 
Thanks a lot for this catch.
