> It was brought up on the mailing list that our Crunch counters are not
> showing up on the Spark webui possibly because they are not named.

> We are currently testing a few capabilities using Spark and one thing we
> noticed in Spark is they don't list any user defined accumulators on web UI.
> On MapReduce I would imagine counters being displayed on the job page,
> however on a SparkPipeline I was only able to pull counter information from
> PipelineResult#getStageResult().
> I think the reason these accumulators are not visible on web UI is because
> crunch does not name these accumulators. Spark expects an accumulator to have
> a name to be visible on the UI.

> (accumulator API with Name)
> I would like to know if it's possible in crunch to name these accumulators so
> they are available in web UI. This will give us an experience where users can
> monitor/watch accumulators from web UI to obtain key information about their
> jobs.
