Sakthi commented on HBASE-22040:
--------------------------------
Ah I see. Yes, the main motto was to try to have multi-region merge feature
accessible via shell (HBASE-22827) be present in 2.1 as well. But that needs
presence of this fix. Do you think it's possible? What would be the best way
forward for users on 2.1 to be able to access this feature. ? [~zhangduo]

> Although we only support merging two regions until now, but the rpc protocol
> does support passing more than two regions to master.
> So I think we should provide the methods, but need to add comments to say
> that for now we only support merging two regions so do not try to pass more
> than two regions.
