Mithun Radhakrishnan commented on HIVE-10024:
---------------------------------------------

I have put this off long enough. The sparse summary and description belie the significance of this fix. It turns out that this wasn't a fix for test-failures at all.

Before this fix, in cases where the last row-group for an ORC stripe contained fewer records than {{$\{orc.row.index.stride\}}}, and when predicate pushdown is enabled, one sees the following sort of failure:

It's a fairly rare case, but leads to bad reads on valid ORC files. This fix is available in {{branch-2}} and forward, but not in {{branch-1}}.
