Vincent Poon commented on PHOENIX-4682:
---------------------------------------
[~jamestaylor] thanks for the review. I only ignore SYSTEM.CATALOG for the
index disabled case, not stats.
I think we need to catch Exception there and not just TableNotFoundException,
because we don't want any other exception (e.g. rpc timeout, etc) to block the
compaction. I just do a special case for TableNotFound because that is
somewhat expected and doesn't need error level logging.
> UngroupedAggregateRegionObserver preCompactScannerOpen hook should not throw

> TableNotFoundException in the preCompactScannerOpen hook can lead to RS abort.
> Some tables might have the phoenix coprocessor loaded but not be actual
> Phoenix tables (i.e. have a row in SYSTEM.CATALOG). We should ignore these
> Exceptions instead of throwing them.
