>
> Some operation ModifyColumnFamily, AddDeleteColumnFamily, DeleteColumnFamily,
> ModifyTable, TruncateTable are still synchronous on the master side. with a
> wait until the operation completes before returning.
> this was done to keep the sync behavior for old client. but instead of using
> the procLatch which recognize the client version and decide if the operation
> should be sync or not it just always wait. making the client side proc fault
> tolerance ineffective.
> also the add/delete/modifyColumnFamily operation does not seems to follow the
> Async() naming in master. and the comment claim to be async but everyone uses
> them as sync. (this is something from HBASE-13538)
