Ankit Singhal commented on HBASE-20642:
---------------------------------------
bq. I don't see what is wrong. You are trying to modify a table adding a column
but you can't because a previous attempt succeeded?
Actually, the scenario is, a user is trying to add a column family in the table
but the master went down after completing half of the states in the
procedure(let's assume the columnFamily was updated in tableDescriptor) , so as
the call is not completed, HBase client will retry the call but it will fail
with InvalidFamilyOperationException
because we don't differentiate if it is retry or a new call.
