Date Thu, 03 Sep 2015 12:48:45 GMT


Micah Whitacre reassigned CRUNCH-558:

    Assignee: Micah Whitacre

> Add name to Spark Accumulators
> ------------------------------
>                 Key: CRUNCH-558
>                 URL:
>             Project: Crunch
>          Issue Type: Improvement
>          Components: Spark
>            Reporter: Micah Whitacre
>            Assignee: Micah Whitacre
> 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.
