Subject [jira] [Created] (HADOOP-9734) Common RefreshUserMappingsProtocol and GetUserMappingsProtocol implementation
Date Mon, 15 Jul 2013 18:30:48 GMT
Jason Lowe created HADOOP-9734:

             Summary: Common RefreshUserMappingsProtocol and GetUserMappingsProtocol implementation
                 Key: HADOOP-9734
                 URL: https://issues.apache.org/jira/browse/HADOOP-9734
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
    Affects Versions: 2.0.4-alpha
            Reporter: Jason Lowe
            Priority: Minor

Many of the Hadoop server daemons support the concept of refreshing user mappings or getting
the currently cached user-group mappings.  Currently there are protocol buffer definitions
of RefreshUserMappingsProtocol and GetUserMappingsProtocol in HDFS, but using it requires
packages to depend upon HDFS when they may otherwise have no reason to do so.  We should move
the protocol buffer definitions and glue code to common for easier reuse.
