---------------------------------
thanks for reporting this bug.
>From a quick analysis on this issue, one possible fix could be adding logic
>into #isRollbackSupported to prevent this from happening.
> Move the table to null rsgroup when creating a existing table

> URL: https://issues.apache.org/jira/browse/HBASE-21866
> Project: HBase
> Issue Type: Bug
> Components: rsgroup
> Reporter: Xiang Li
> Assignee: Xiang Li
> Priority: Major
>
> By using the latest HBase master branch, the bug could be re-produced as:
> # create 't1', 'cf1'
> # create 't1', 'cf1'
> The following message is logged into HMaster's log:
> {code}
> INFO [PEWorker-12] rsgroup.RSGroupAdminServer: Moving table t1 to RSGroup
> null
> {code}
> This is a wrong action that we should keep t1 as where it originally is.
