[jira] [Created] (HIVE-18318) LLAP record reader should check interrupt

Sergey Shelukhin created HIVE-18318:
---------------------------------------

             Summary: LLAP record reader should check interrupt
                 Key: HIVE-18318
                 URL: https://issues.apache.org/jira/browse/HIVE-18318
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


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.
