Ted Yu commented on HBASE-20666:
--------------------------------
For #1, I see that you have an assertion in finally block which is equivalent
to what I suggested.
Basically you can put Assert.fail() call following table creation since you
know that table creation would throw exception.
> Unsuccessful table creation leaves entry in rsgroup meta table

> 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.
