I rebased this PR to latest master and [re-ran functional
test](http://10.10.104.91:8080/job/Functional/2447/console) and seeing only 2
random failures now. As per @agirish recommendation I have created JIRA's to
track these random issues.
[DRILL-5788](https://issues.apache.org/jira/browse/DRILL-5788) &
