Duo Zhang commented on HBASE-22121:
-----------------------------------

The error prone warning is still a bit unstable...Not sure why, maybe we should 
open an issue on the error prone project as we have already upgraded to the 
newest version...

> AsyncAdmin can not deal with non default meta replica

> In AsyncAdmin we support passing both encodedRegionName and regionName as a 
> parameter so we have a getRegionInfo method to get the RegionInfo first.
> In general we will scan the meta table to get the region info, but for meta 
> region itself, the problem is that, we only check for the first replica, so 
> for the non default replicas, we will still go to the meta region and then 
> get an UnknownRegionException.
> We should find a way to deal with this.
