> When pipeline.run() is called, MetricsAccumulator (wrapper of
> MetricsContainerStepMap spark accumulator) is initialized. Spark needs this
> class to be a singleton for failover. The problem is that when several
> pipelines are run inside the same JVM, the initialization ofÂ
> MetricsAccumulator singleton does not reset the underlying spark accumulatorÂ
> causing metrics to be accumulated between runs.
