LGTM - +1
AFAIK, the operator issue was logged before - HIVE-15889
> LLAP record reader should check interrupt even when not blocking

> Hive operators don't check interrupts, and may not do blocking operations.
> LLAP record reader only blocks in IO is slower than processing; so, if IO is
> fast enough, it will not ever block (at least not interruptibly, the sync
> w/IO on the object does not check interrupts), and thus never catch
> interrupts.
> So, the task would be impossible to terminate.
