Ashwin Shankar updated MAPREDUCE-5265:
--------------------------------------
Attachment: JHS_REFRESH-2.txt
This patch(JHS_REFRESH-2.txt) contains all the features mentioned in the
description. On a high level I've changed 'mapred' shell script to incorporate
the new 'hsadmin' commands. I've created a client(which is instantiated by
shell script),the client rpc stub,protocol buffer rpc messages,server rpc
stub,admin server which executes the command.NOTE : I've not written unit tests
yet. I wanted to get comments first so that I don't have to rewrite tests in
case there are major comments .
> Need an admin interface on history server with the ability to refresh super
> user groups,refresh user to group mappings,refresh admin acls,get groups
> given a username.

> 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.
