Assignee: Michael Smith (was: Henry Robinson)
> Reword datastream timeout error message to highlight situations where
> changing the timeout makes sense

> Key: IMPALA-3978
> URL: https://issues.apache.org/jira/browse/IMPALA-3978
> Project: IMPALA
> Issue Type: Improvement
> Components: Distributed Exec
> Affects Versions: Impala 2.7.0
> Reporter: Henry Robinson
> Assignee: Michael Smith
> Priority: Major

> This error message:
> {quote}
> Datastream sender timed-out waiting for recvr for fragment instance:
> 9f4cdc5cf9c63511:3ad1e5076f9a41e2 (time-out was: 2m).
> Increase --datastream_sender_timeout_ms if you see this message frequently.
> {quote}
> is printed out no matter what the cause of the timeout. However, increasing
> the timeout only really makes sense if the system is overloaded, i.e.
> fragments are being started but they're taking a very long time. We should
> reword the message to make the clearer, so when timeouts are being hit due to
> failures, users don't think they have to reconfigure the system.
