Dmitriy V. Ryaboy commented on PIG-1746:
----------------------------------------
Kevin, we already have that -- the jobs are named after the file (if you run
pig myfile.pig), but you can override the name with "set job.name myname"
With this ticket, that job name would essentially become a prefix.
> Pig MR jobs should have descriptive names

> 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).
