> I think the reason for the check is that table creation without family is allowed before
HBASE-15456. With HBASE-15456, table creation without family is not allowed. We have one user
claimed that they run into the same HRegionServer$PeriodicMemstoreFlusher exception, and the
table was created with family. The log was not kept so could not find more info there.  By
checking the code, it seems impossible. Can we undo this check so the real issue is not hidden
in case there is one, [~Apache9]?
