Jesus Camacho Rodriguez resolved HIVE-11165.
--------------------------------------------
    Resolution: Cannot Reproduce

I explored this one, and we could not reproduce it the problem. Agreed with [~gopalv] that
if it showed up again, we would re-open the issue.

> After about 6 minutes trying to plan a query, the HiveServer2 was killed to restore functionality
to a test run.
> The HEP planner is stuck on a TopologicalOrder traversal and there were no queries being
fed into the HiveServer2 after it got stuck.
> TPC-DS query13 was the query in question, at 4 way parallel, which triggered the issue.
