Subject [jira] [Created] (HIVE-4812) Explain plan for physical operators

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

             Summary: Explain plan for physical operators
                 Key: HIVE-4812
                 URL: https://issues.apache.org/jira/browse/HIVE-4812
             Project: Hive
          Issue Type: Bug
            Reporter: Gunther Hagleitner
            Assignee: Gunther Hagleitner


In various situations it would have been useful to me to glance at the operator plan before
we break it into tasks and apply join, total order sort, etc optimizations.

I've added this as an options to explain. "Explain physical <QUERY>" will output the
full operator tree (not the stage plans, tasks, AST etc).

Again, I don't think this has to even be documented for users, but might be useful to developers.
