Subject [jira] [Commented] (HDFS-5322) HDFS delegation token not found in cache errors seen on secure HA clusters
Date Wed, 09 Oct 2013 16:30:45 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13790583#comment-13790583
] 

Daryn Sharp commented on HDFS-5322:
-----------------------------------

I think this change will also break yarn which is why I was hesitant to change the signatures.

Do you know why checkOperation isn't throwing the expected StandbyException?
