Subject [Impala-ASF-CR] IMPALA-5892: Allow reporting status independent of fragment instance
Date Wed, 06 Sep 2017 17:14:52 GMT
Hello Dan Hecht,

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#3).

Change subject: IMPALA-5892: Allow reporting status independent of fragment instance

IMPALA-5892: Allow reporting status independent of fragment instance

Queries can hit an error that is not specific to a
particular fragment instance. For example, QueryState::StartFInstances()
calls DescriptorTbl::Create() before any fragment instances
start. This location has no reason to report status via a
particular fragment, and there is currently no way to report
status otherwise. This leads to a query hang, because the
status is never propagated back to the coordinator.

This adds the ability to report status that is not associated
with a particular fragment instance. By reporting status,
the coordinator will now correctly abort the query in the
case of the QueryState::StartFInstances() scenario described.
