Vincent Poon commented on PHOENIX-4242:
---------------------------------------
[~jamestaylor]
In our postCompact hook, we call getTableNoCache which calls
MetaDataClient#updateCache. However in there, we bail out early if it's a
System table, instead of populating the result.

If I comment out that portion, then my test passes for the NPE part of this
Jira. Any idea if/why we need this?
> 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
>
> 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:
> 2017-09-28 13:35:03,118 WARN [ctions-1506410238599] index.Indexer - Unable
> to permanently disable indexes being partially rebuild for SYSTEM.SEQUENCE
> java.lang.NullPointerException

> org.apache.phoenix.schema.TableNotFoundException: ERROR 1012 (42M03): Table
> undefined. tableName=MERGE_PLATFORM_ENTITY.PLATFORM_IMMUTABLE_ENTITY_DATA2
