-----------------------------------

             Summary: RBF : GetServerDefaults Should be Cached At Router
                 Key: HDFS-15096
                 URL: https://issues.apache.org/jira/browse/HDFS-15096
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Ayush Saxena
            Assignee: Ayush Saxena


Presently each getServerDefault calls are triggered to the Namespace, The DFSClient caches
the getServerDefaults(), similarly the Router can also cache the getServerDefaults(), as router
connects to multiple clients, this improves performance for subsequent calls.
