Samarth Jain commented on PHOENIX-3230:
---------------------------------------
We could still have the initializationException code path. We could be a little
smart and set initializationException when the exception is not an instance of
IOException. If it is an instance of IOException, then set it only if it is an
instance of DoNotRetryIOException.
> SYSTEM.CATALOG get restored from snapshot with multi-client connection

> If two separate Phoenix connections try to upgrade Phoenix from v4.7 to 4.8.1
> then second connection fails with the following exception. This happens even
> if second connection is couple of seconds apart but within upgrade window.
> This is likely to happen in situation where pool of client machines all get
> upgraded to latest Phoenix version. After this exception, all clients will
> cease to work with undefined column exception due to restore/aborted upgrade.
