> If there is only one family in the table, DeleteColumnFamilyProcedure will fail. 
> Currently, when hbase.table.sanity.checks is set to false, hbase master logs a warning
and CreateTableProcedure/ModifyTableProcedure will succeed. 
> This behavior is not consistent with DeleteColumnFamilyProcedure's. 
> Another point, before HBASE-13145, PeriodicMemstoreFlusher will run into the following
exception. lastStoreFlushTimeMap is populated for families, if there is no family in the table,
there is no entry in lastStoreFlushTimeMap.
