Subject [jira] [Created] (HDFS-10391) Always enable NameNode service RPC port
Date Wed, 11 May 2016 23:47:12 GMT
Arpit Agarwal created HDFS-10391:
------------------------------------

             Summary: Always enable NameNode service RPC port
                 Key: HDFS-10391
                 URL: https://issues.apache.org/jira/browse/HDFS-10391
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode, namenode
            Reporter: Arpit Agarwal


The NameNode should always be setup with a service RPC port so that it does not have to be
explicitly enabled by an administrator.

This change can be made in a backwards-compatible manner so that DataNodes fallback to the
client RPC port if the service RPC port is unavailable.
