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

             Summary: Calcite planner might have a thread-safety issue compiling in parallel
                 Key: HIVE-11165
                 URL: https://issues.apache.org/jira/browse/HIVE-11165
             Project: Hive
          Issue Type: Bug
          Components: CBO
    Affects Versions: 2.0.0
            Reporter: Gopal V


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.
