Thiruvel Thirumoolan commented on HBASE-18062:
----------------------------------------------
All favored admin APIs have a group and non-group version. Was planning to do
both of them together. The group version of APIs would need
FavoredRSGroupBalancer patch (HBASE-15533). That couldn't be pushed because we
couldn't get the precommit builds to run (as rsgroups tests don't work,
HBASE-18110).
If enabling rsgroups tests would take a little bit of time, I can start with
the non-group version of the APIs.

> From the design doc:
> This command is useful while decommissioning a server. It removes the
> specified server (hostname:port) as favored node from regions. This operation
> does not change any assignments, but alters favored node information in
> hbase:meta. The users have to make sure that the specified server is not
> hosting any regions. Since region servers go down much more frequently than
> datanodes, the admin has to use this tool when decommissioning a datanode and
> region server.
