> There were many regressions recently wrt ORC predicate pushdown. We don't
> have system tests to capture these regressions. Currently there is only junit
> tests for testing ORC predicate pushdown feature. Since hive counters are not
> available during qfile test execution there is no easy way to verify if ORC
> PPD feature worked or not. This jira is add a post execution hook to print
> hive counters (esp. number of input records) to error stream so that it will
> appear in qfile test output. This way we can verify ORC SARG evaluation and
> avoid future regressions.
