Ankit Singhal commented on HBASE-20642:
---------------------------------------
bq.On their first submission, they get this? I don't follow. Is it something to
do w/ Master going down?
Yes, they will get this on their first submission if the master goes down in
between.
bq. What retrying mechanism is this? Is this the (deprecated) addColumn –
synchronous call? Are you seeing the call move from the dead Master to the new
Master?
This is addColumnFamily() synchronous call and it is getting moved to the new
master.
bq. I like the idea of putting all behind Nonces but nonce are no good if the
Master is swapped during the call?
If the master is swapped, nonces map will be rebuilt from uncompleted procedure
during the replay so we should not have a problem checking on the new master as
well. right?
{quote}Thanks for helping me understand.{quote}
No problem, probably I'm not putting the problem in right words [~stack]
