The DelegationTokenRenewal timer task should use the jobtracker's credentials
to create the filesystem
------------------------------------------------------------------------------------------------------
Key: MAPREDUCE-1559
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1559
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobtracker
Affects Versions: 0.22.0
Reporter: Devaraj Das
Assignee: Devaraj Das
Fix For: 0.22.0
The submitJob RPC finally creates a timer task for renewing the delegation
tokens of the submitting user. This timer task inherits the context of the RPC
handler that runs in the context of the job submitting user, and when it tries
to create a filesystem, the RPC client tries to use the user's credentials.
This should instead use the JobTracker's credentials.
