could you please take a look @rbalamohan, @jteagles? very small patch, unit test included

[jteagles]

+1. This will need to go to branch-0.9 as well since TEZ-4157 is in master and branch-0.9 I believe.

[abstractdog]

thanks for the review @jteagles, I'm merging, I'll check if we need this on branch-0.9, not because of TEZ-4157, because that wasn't the root cause actually
