Subject [jira] [Commented] (PHOENIX-4242) Fix Indexer post-compact hook logging of NPE and TableNotFound
Date Tue, 10 Oct 2017 21:23:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-4242?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16199388#comment-16199388
] 

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.

> 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.
