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. https://github.com/apache/crunch/blob/apache-crunch-0.13.0/crunch-spark/src/main/java/org/apache/crunch/impl/spark/SparkRuntime.java#L125-L126 https://github.com/apache/spark/blob/v1.4.1/core/src/main/scala/org/apache/spark/api/java/JavaSparkContext.scala#L616-L624 (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. Thanks, Nithin
