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

             Summary: Include number of required threads in explain plan
                 Key: IMPALA-6957
                 URL: https://issues.apache.org/jira/browse/IMPALA-6957
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
    Affects Versions: Not Applicable
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong


Impala has an internal notion of "required threads" to execute a fragment, e.g. the fragment execution thread and the first scanner thread. It's possible to compute the number of required threads per fragment instance based on the plan.

We should include this in the resource profile and expose it in the explain plan. This could then be a step toward implementing something like IMPALA-6035.
