> 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.
