Amit Sela commented on BEAM-891:
--------------------------------

This seems to be the race: https://github.com/apache/spark/blob/branch-1.6/streaming/src/main/scala/org/apache/spark/streaming/StreamingContext.scala#L711

As the {{StreamingContext}} get's the {{env}}'s metricsSystem, which uses the same {{MetricsSystem}} as we use in {{SparkRuntimeContext}}.
In general, Spark's {{ENV}} modules are singletons.
