> Hitting "Timed out waiting for heartbeat for task ID" errors with the LLAP
> external client.
> HIVE-17393 fixed some of these errors, however it is also occurring because
> the client is not correctly handling the killTask notification when the
> request is accepted but still waiting for the first task heartbeat. In this
> situation the client should retry the request, similar to what the LLAP AM
> does. Current logic is ignoring the killTask in this situation, which results
> in a heartbeat timeout - no heartbeats are sent by LLAP because of the
> killTask notification.
