> 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.
