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.
