Josh Wills commented on CRUNCH-272:
-----------------------------------
The MRPipeline constructor has an option to specify a string that is used as a
common name for all of the MR jobs kicked off by that pipeline: could your
JavaAction pass a string in via the commandline that could be passed to the
MRPipeline instance, and used to track the jobs that were spawned by the action?
> Unable to correlate crunch jobs within Oozie

> Project: Crunch
> Issue Type: Improvement
> Reporter: Mike Zimmerman

> 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.
