Subject [jira] [Commented] (HIVE-15680) Incorrect results when hive.optimize.index.filter=true and same ORC table is referenced twice in query
Date Wed, 01 Feb 2017 01:59:52 GMT

    [ https://issues.apache.org/jira/browse/HIVE-15680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15847877#comment-15847877

Sergey Shelukhin commented on HIVE-15680:
-----------------------------------------

The issue at least in some tests seems to be the continuation of HIVE-15649 that I've fixed
recently. I will fix this shortly, probably today.

> To repro:
> {noformat}
> set hive.optimize.index.filter=true;
> create table test_table(number int) stored as ORC;
> -- Two insertions will create two files, with one stripe each
> insert into table test_table VALUES (1);
> insert into table test_table VALUES (2);
> -- This should and does return 2 records
> select * from test_table;
> -- These should and do each return 1 record
> select * from test_table where number = 1;
> select * from test_table where number = 2;
> -- This should return 2 records but only returns 1 record
> select * from test_table where number = 1
> union all
> select * from test_table where number = 2;
> {noformat}
> What's happening is only the last predicate is being pushed down.
