Subject [jira] [Updated] (HDFS-10391) Always enable NameNode service RPC port
Date Sat, 09 Sep 2017 17:05:03 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10391?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arpit Agarwal updated HDFS-10391:
---------------------------------
       Resolution: Fixed
     Hadoop Flags: Incompatible change,Reviewed  (was: Incompatible change)
    Fix Version/s: 3.0.0-beta1
     Release Note: The NameNode service RPC port is enabled by default. This port is used
by the NameNode to accept non-client requests i.e. requests from other HDFS services namely
the DataNodes, ZooKeeper Failover Controllers and the Secondary NameNode. The default service
RPC port is 9840. It can be changed via the configuration key dfs.namenode.servicerpc-address.
           Status: Resolved  (was: Patch Available)

I've committed this to trunk. Thanks for the contribution [~GergelyNovak] and for the review
[~xyao].

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