> 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.
