-------------------------------------
Summary: Add general mechanism to find DataSink from other
fragments
Key: IMPALA-9125
URL: https://issues.apache.org/jira/browse/IMPALA-9125
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Tim Armstrong
Assignee: Tim Armstrong
As a precursor to IMPALA-4224, we should add a mechanism for an finstance to
discover the join build sink from another finstance.
We already have a related single-purpose mechanism in the coordinator to find
PlanRootSink. We should generalise this to allow looking up the sink of any
other finstance and move it into QueryState
