Description

It looks like it might be a case of the starving-out-the-queue issue, but this time a valid query cannot run even in absence of errors.
It could also be something else (reducers being stuck?)
I ran on 10 nodes... with mode == map, query finishes.
With reducers in LLAP, it's stuck at this stage:

Map 1 ..........      llap   SUCCEEDED     31         31        0        0       0       0
