-------------------------------------

             Summary: Compute stats profiles should include reference to child queries
                 Key: IMPALA-6924
                 URL: https://issues.apache.org/jira/browse/IMPALA-6924
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 3.0, Impala 2.12.0
            Reporter: Tim Armstrong


"Compute stats" queries spawn off child queries that do most of the work. It's non-trivial to track down the child queries and get their profiles if something goes wrong. We really should have, at a minimum, the query IDs of the child queries. in the profile. Maybe we could do better than that.
