------------------------------------
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.
