Subject [jira] [Created] (HDFS-2746) Add a parameter to `hdfs dfsadmin -saveNamespace' to allow an arbitrary storage dir

Add a parameter to `hdfs dfsadmin -saveNamespace' to allow an arbitrary storage dir
-----------------------------------------------------------------------------------

                 Key: HDFS-2746
                 URL: https://issues.apache.org/jira/browse/HDFS-2746
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: name-node
    Affects Versions: 0.24.0
            Reporter: Aaron T. Myers


Presently `hdfs dfsadmin -saveNamespace' will attempt to save a snapshot of the file system
metadata state into all configured storage dirs. It would be nice if we could optionally specify
an arbitrary local dir to save the FS state into, instead of the configured storage dirs.
