    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.
