             Summary: some parts of the Driver runs from the "Background-Pool" in HS2
                 Key: HIVE-19093
                 URL: https://issues.apache.org/jira/browse/HIVE-19093
             Project: Hive
          Issue Type: Bug
            Reporter: Zoltan Haindrich


I was looking into perflog results; and the fact that Driver.run open / close happens on a different thread caught my eye - this might cause real problems since {{Session.get()}} will return an entirely different session in the aftermath...most notably there are some lock related calls like: releaseLocks
