Jitendra Nath Pandey updated MAPREDUCE-1824:
--------------------------------------------
Description: In trunk, the DelegationTokenRenewal obtains the file system
handle by creating the uri out of service in the token, which is ip:port. The
intention of this jira is to use host name of the namenode so that fils system
handle in the cache on jobtracker could be re-used. This jira is created
because such an optimization is there in 20 code and the patch attached is the
direct port of the code in 20.
> JobTracker should reuse file system handle for delegation token renewal
