Josh Wills commented on CRUNCH-272:
-----------------------------------
I like the ideas in this patch-- should the Pipeline object have a way of
tracking all of the PipelineResult objects that corresponded to any jobs that
were run in the life of the Pipeline so that we can get around the
materialize() cases?
> Unable to correlate crunch jobs within Oozie

> I'm not really sure if this should be logged to Oozie or to Crunch, so please
> feel free to move as needed.
> I would like to request a way to decorate map/reduce jobs that are spawned by
> a Crunch pipeline so that I can programmatically determine their origin. The
> primary use case for this is integration with Oozie. Oozie launches a single
> map job to run a java action (in our case this java action runs a crunch
> job). Traceability from this original "launcher" job to the jobs created by
> the crunch job is impossible without trolling logs. This leaves a big black
> hole for the system operator to assess the performance/impact of these jobs.
> My initial thought was to provide a simple way to indicate a correlationId or
> similar on a map/reduce job and then make it accessible within Oozie to query
> for. Obviously, that request would have to come after the correlation
> feature was available within map/reduce.
