Aniket Bhatnagar updated SPARK-8895:
------------------------------------
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:
{quote}
[info] o.a.s.m.MetricsSystem -Metrics already registered
java.lang.IllegalArgumentException: A metric named
