[jira] [Created] (IMPALA-7830) Improve Scheduler Tracing

Lars Volker created IMPALA-7830:
-----------------------------------

             Summary: Improve Scheduler Tracing
                 Key: IMPALA-7830
                 URL: https://issues.apache.org/jira/browse/IMPALA-7830
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Lars Volker


The behavior of the scheduler is often difficult to understand. We should add tracing of its inputs (scan range, block location metadata), its decisions, and the resulting schedule. This should be configurable by a query option and/or a query hint, and should optionally be written into the log and/or the profile.
