      Description

      StreamingContext calls env.metricsSystem.registerSource during its construction but does not call env.metricsSystem.removeSource. Therefore, if a user attempts to restart a Streaming job in the same JVM by creating a new instance of StreamingContext with the same application name, it results in exceptions like the following in the log:

      [info] o.a.s.m.MetricsSystem -Metrics already registered
      java.lang.IllegalArgumentException: A metric named <AppName>.StreamingMetrics.streaming.lastReceivedBatch_processingEndTime already exists
