> AsyncAdmin can not deal with non default meta replica
> -
>
> Key: HBASE-22121
> URL: https://issues.apache.org/jira/browse/HBASE-22121
> Project: HBase
>  Issue Type: Bug
>  Components: Admin, asyncclient, Client
>Reporter: Duo Zhang
>Assignee: Duo Zhang
>Priority: Major
> Fix For: 3.0.0, 2.2.0, 2.3.0, 2.1.5
>
> Attachments: HBASE-22121.patch
>
>
> 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.
