Geoffrey Jacoby commented on PHOENIX-4682:
------------------------------------------
[~vincentpoon]- I think you should also add in a check to skip this coprocessor
logic when the major compaction is of System.Catalog itself, since the logic
queries System.Catalog.
Wrt to [~apurtell]'s comment about potentially letting an IOException through –
keep in mind that the call to PhoenixRuntime.getTableNoCache is a potentially
remote call to another RS, and at no time should a timeout or problem with that
call lead to a thrown IOException out of here if that's going to potentially
kill the RS. I think the original issue title should stand.

> 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.
