Subject [jira] [Commented] (PHOENIX-2446) Immutable index - Index vs base table row count does not match when index is created during data load
Date Fri, 22 Jan 2016 00:33:39 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2446?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15111684#comment-15111684
] 

James Taylor commented on PHOENIX-2446:
---------------------------------------

+1. Couple of fix-on-commit nits: remove commented out code in PostLocalIndexDDLCompiler and
make sure indenting is correct in MetaDataClient (and other places).

Thanks, [~tdsilva] - nice work. Do your manual tests all pass too?

> I'll add more details later but here's the scenario that consistently produces wrong
row count for index table vs base table for immutable async index.
> 1. Start data upsert
> 2. Create async index
> 3. Trigger M/R index build
> 4. Keep data upsert going in background during step 2,3 and a while after M/R index finishes.
> 5. End data upsert. 
> Now count with index enabled vs count with hint to not use index is off by a large factor.
Will get a cleaner repro for this issue soon.
