This is a good suggestion. In current versions, your pig query is in a file,
the file name is part of the job name. But all MR jobs for the query have
this same name. Having relation name as part of job name might not be very
useful as the mapping of relation to MR job is not 1:1 .
I think a name of the form "PigLatin:name:mrid" will be useful. 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).
Can you please open a jira for this feature ?
