Subject [jira] [Commented] (HDFS-4548) Webhdfs doesn't renegotiate SPNEGO token
Date Wed, 03 Apr 2013 17:35:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13621088#comment-13621088
] 

Alejandro Abdelnur commented on HDFS-4548:
------------------------------------------

Daryn, I'm OK with the fix itself(you have my +1). It just that we had a string of JIRAs 'tweaking'
things here and there for DelegationToken and SPNEGO instead taking a step a back a fixing
things properly.

> When the webhdfs SPNEGO token expires, the fs doesn't attempt to renegotiate a new SPNEGO
token.  This renders webhdfs unusable for daemons that are logged in via a keytab which would
allow a new SPNEGO token to be generated.
