     [ https://issues.apache.org/jira/browse/MAPREDUCE-5265?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ashwin Shankar updated MAPREDUCE-5265:
--------------------------------------

    Target Version/s: 2.1.0-beta, 0.23.9  (was: 0.23.8, 2.0.5-alpha)
              Status: Patch Available  (was: Open)

I have changed my rpc layer implementation to use classes from hadoop-common rather than Yarn rpc. I've also incorporated the comments suggested. This patch includes units tests. However please note that this patch doesn't apply to branch-23.

> The history server needs an admin interface with the ability to
> 1. refresh the super user groups configurations,
> 2. refresh user to group mappings,
> 3. refresh its admin acls,
> 4. get groups given a username 
> without requiring a restart of the history server.  This is analogous to the  -refreshSuperUserGroupsConfiguration capabilities provided by hdfs dfsadmin and yarn rmadmin.
