Subject [jira] Commented: (MAPREDUCE-1433) Create a Delegation token for MapReduce
Date Tue, 09 Feb 2010 09:01:29 GMT

Devaraj Das commented on MAPREDUCE-1433:
----------------------------------------

Looks good. You need to fix JobTracker.renewDelegationToken to actually do the renewal (there
is a copy-paste error there *smile*)

> Occasionally, MapReduce jobs need to launch other MapReduce jobs. With security enabled,
the task needs to authenticate to the JobTracker as the user with a token.
