    Description

      See a lot of following warnings during Hadoop job running

      ERROR 11:37:45 LEAK: You are creating too many HashedWheelTimer instances.  HashedWheelTimer is a shared resource that must be reused across the JVM,so that only a few instances are created.

      Each cluster/session needs be closed and a shared HashedWheelTimer may reduce the resource leakage.
