> If a table creation fails in a cluster enabled with {{rsgroup}} feature, the table is still listed as part of {{default}} rsgroup.
> To recreate the scenario:
> - Create a namespace (NS) with number of region limit
> - Create table in the NS which satisfies the region limit by pre-splitting
> - Create a new table in the NS which will fail
> - {{list_rsgroup}} will show the table being part of {{default}} rsgroup and data can be found in {{hbase:rsgroup}} table
> Would be good to revert the entry when the table creation fails or a script to clean up the metadata.
