Kevin Burton commented on PIG-1746:
-----------------------------------
Another idea I was thinking of today, is the ability to specify a prefix for
the job ID on the command line.
So if you have an algorithm that has params and is 'named' then the list of
jobs in the job tracker will be descriptive.
Maybe for example 'index_en' or 'index_fr' for some algorithm that indexes
english and french content.
I was looking at the code recently on who the job name was specified and
perhaps reading from a generic system property could be the solution to this.
-Dpig.job.prefix=index_en

> Pig should assign an informative name to each of the MR Job generated in Pig
> Physical plan. Maybe name of the relation itself. Another suggestion is to
> assign name of the form "PigLatin:name:mrid", where name is the name of the
> query file, or 'set job.name' or PigServer.setJobName() and mrid is an id
> corresponding to each MR job, and this id would be printed in output of
> explain command (which also shows what relations are corresponding to the MR
> job).
