-------------------------------------
Hi [~vinayrpet],
Thanks for your reply. My question was, this jira suggest to ignore
StandbyException, but the fix only check RemoteException. RemoteException could
wrap exceptions other than StandbyException. Should we treat the other kind of
exceptions wrapped by RemoveException the same as StandbyException (the current
fix does that), or we should do more checking to handle StandbyException only
this way? Thanks.
