Nihal Jain commented on HBASE-21645:
------------------------------------
{quote}IMO we should also set region replica count as 1 in descriptor if table
creation is allowed in this case.
{quote}
This can be done, but if we do this we should handle it consistently all
across. What I mean is currently if we try to create/modify table with say, min
version with a negative illegal value, we throw/warn but do not override the
value.
We should handle the over-riding of incorrect/meaningless value for all such
cases.
> Perform sanity check and disallow table creation/modification with region
> replication < 1
