Prasanth J updated HIVE-6786:
-----------------------------
Description:
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?
Stack trace will look like:
{code}
Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
