Subject [jira] [Created] (HDFS-7519) Support for a Reconfigurable NameNode
Date Sat, 13 Dec 2014 00:39:13 GMT
Mike Yoder created HDFS-7519:

             Summary: Support for a Reconfigurable NameNode
                 Key: HDFS-7519
                 URL: https://issues.apache.org/jira/browse/HDFS-7519
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 2.6.0
            Reporter: Mike Yoder

The DataNode gained the use of the "Reconfigurable" code in HDFS-6727.  The purpose of this
jira is to also use the Reconfigurable code in the Namenode.

Use cases:
* Take the variety of refresh-something-in-the-namenode RPCs and bring them all under one
* Allow for future reconfiguration of parameters, and parameters that plugins might make use
