>
> Beam metrics shown in Spark history server are not readable. They're rendered
> as JSON which is created from protobuffer defined in *beam_job_api.proto*
> where metric's value is defined as bytes.
> Similar issue was already addressed and fixed in BEAM-6062 but was broken by
> BEAM-4552.
> Solution could be using *SparkMetricsContainerStepMap* instead of
> *MetricsContainerStepMap* inside *MetricsContainerStepMapAccumulator* as in
> BEAM-6062.
