Kevin Wilfong commented on HIVE-3484:
-------------------------------------
There are classes of errors that would be suitable to retry at the raw store
level (in which the transaction is maintained open) and classes of errors that
should be retried at the Hander level (in which the transaction is rolled
back/lost).
It's up to Jean how much she wants to accomplish in this JIRA, but when I
suggested she work on this task, I was hoping for at least an implementation of
something which could retry outside of transactions, determining those classes
of errors that should be handled in either the raw store or the handler could
be done here or as part of another JIRA.
