---------------------------------
Summary: Better semantic and handling for kill()
Key: DRILL-641
URL: https://issues.apache.org/jira/browse/DRILL-641
Project: Apache Drill
Issue Type: Improvement
Reporter: Mehant Baid
Currently when an operator invokes kill(), only the upstream operators within
that fragment get terminated. This causes problems if the upstream operator in
a different fragment is still continuously producing batches, and it then
becomes the responsibility of the operator to drain all the batches even though
a kill was issued.
While dealing with plans with multiple fragments we would need to inform the
sender that a kill has been invoked. It would then be the responsibility of the
sender to not push any more batches to the corresponding receiver.
