> 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 of MetricsAccumulator singleton does not reset the underlying spark accumulator causing metrics to be accumulated between runs.
