Guanghao Zhang commented on HBASE-21645:
----------------------------------------
What will happed if replica config to 0? There will no regions for the table?
And please add the table name to the message. Why not use
warnOrThrowExceptionForFailure to keep same pattern with other checks?
> Perform sanity check and disallow table creation/modification with region
> replication < 1
