Vincent Poon commented on PHOENIX-4242:
---------------------------------------
[~jamestaylor] Does it matter if the index table gets compacted? If the data
table is being compacted, if the indexes on it are disabled, then we don't want
to remove crucial version history for rebuilding the index. But does it matter
if we clear the index table version history, whether it's disabled or not? We
don't seem to ever scan through the index version history anywhere.
> Fix Indexer post-compact hook logging of NPE and TableNotFound

> Key: PHOENIX-4242
> URL: https://issues.apache.org/jira/browse/PHOENIX-4242
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.12.0
> Reporter: Vincent Poon
> Assignee: Vincent Poon
> Attachments: PHOENIX-4747.v1.master.patch

>
> The post-compact hook in the Indexer seems to log extraneous log messages
> indicating NPE or TableNotFound. The TableNotFound exceptions seem to
> indicate actual table names prefixed with MERGE or RESTORE, and sometimes
> suffixed with a digit, so perhaps these are views or something similar.
> Examples:
