Sergey Shelukhin commented on HIVE-18318:
-----------------------------------------
The operator stuff is not really an issue, it's more like a semi deliberate
design omission.
Abort flag is only checked in some init methods; no operator has a mechanism to
check it anywhere, so it's not like there are some problematic operators.
> 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.
