Subject [jira] [Created] (HIVE-6786) Off by one error in ORC PPD
Date Sat, 29 Mar 2014 05:02:14 GMT
Gopal V created HIVE-6786:
-----------------------------

             Summary: Off by one error in ORC PPD 
                 Key: HIVE-6786
                 URL: https://issues.apache.org/jira/browse/HIVE-6786
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.13.0
            Reporter: Gopal V
            Priority: Critical


Turning on ORC PPD makes split computation fail for a 10Tb benchmark.

Narrowed down to the following code fragment

https://github.com/apache/hive/blob/branch-0.13/ql/src/java/org/apache/hadoop/hive/ql/io/orc/OrcInputFormat.java#L757

{code}
                includeStripe[i] = (i > stripeStats.size()) ||
                    isStripeSatisfyPredicate(stripeStats.get(i), sarg,
                                             filterColumns);
{code}

I would guess that should be a >=, but [~prasanth_j], can you comment if that is the right
fix?
