Michael Ho commented on IMPALA-539:
-----------------------------------
Given that we probably need a timeout for response of the cancellation RPC
issued by the coordinator, we probably need to think through what the
relationship it may have with IMPALA-2990. In IMPALA-2990, a query will be
cancelled if a particular backend hasn't reported any status for a certain
timeout period. If fixing this Jira means waiting for backends to reply during
cancellation, this may lengthen the overall timeout of hung queries due to
unresponsive backends.
> Impala should gather final runtime profile from fragments for
> aborted/cancelled query

> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 1.1
> Reporter: Alan Choi
> Priority: Minor
> Labels: query-lifecycle
>
> For cancelled/aborted queries, the final runtime profile from plan fragments
> are not recorded and reported by the coordinator. For short running queries,
> we won't see any profile at all because no intermediate runtime profile has
> been sent.
