Subject [jira] [Commented] (CRUNCH-272) Unable to correlate crunch jobs within Oozie
Date Wed, 02 Oct 2013 18:33:47 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-272?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13784257#comment-13784257
] 

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?

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.
