      Description

      A synchronized block is used in "org.apache.hive.jdbc.HiveConnection.SynchronizedHandler.invoke(Object, Method, Object[])" to synchronize the client invocations. The problem is that it does not guarantee any fairness. One issue we were seeing is that a cancellation request was not able to be issued to HS2 until all the getOperationStatus() calls are finished from a while loop. Thus the cancellation cannot take effect.
