> Still after the fun I had over in HBASE-4729, I tried to finish altering my table (remove
a family) since only half of it was changed so I did this:
> {quote}
> hbase(main):002:0> alter 'TestTable', NAME => 'allo', METHOD => 'delete' 
> Updating all regions with the new schema...
> 244/244 regions updated.
> Done.

> Nice it all looks good, but over in the master log:
> {quote}
> org.apache.hadoop.hbase.InvalidFamilyOperationException: Family 'allo' does not exist
so cannot be deleted
