Vihang Karajgaonkar commented on HIVE-19505:
--------------------------------------------
Changing from 2 to 3 didn't help much. The execution phase came down from ~1 hr
30 min to ~ 1hr 20 min. Ideally should have been close to ~1hr. This shows
that the bottleneck is may be some where else. I think we are spending a lot of
time copying the files which are close to 20G. See HIVE-19487
> Increase number of parallel runs from 2 per node to 4

> The test cluster is under utilized. For the short run we can increase the
> parallel threads from 2 to 3 (or may be 4) which will speedup parallel test
> batches.
