Subject [jira] Updated: (MAPREDUCE-1430) JobTracker should be able to renew delegation tokens for the jobs
Date Sun, 21 Feb 2010 19:45:28 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1430?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Devaraj Das updated MAPREDUCE-1430:
-----------------------------------

    Attachment: 1430-dd3.patch

Puts back the LOG.info for the delegation token renewal registration. I also removed the call
to DelegationTokenRenewal.close from JobTracker.close. After thinking on this aspect it seemed
to make sense to not cancel the tokens that the JobTracker didn't own in the first place.
Also, when the JobTracker restarts, it can continue to run the jobs that were running earlier,
if the delegation tokens are not cancelled. The tokens will die their natural death if no
one renews them...
