Julien Le Dem commented on PIG-2658:
------------------------------------

I do agree that those are generic, ideally we define those names in Hadoop to favor reuse.

> The overall identifier for a pig script pig.script.id added in PIG-1280 ties together the various map-reduce jobs generated for a script.
> It would be good to have a timestamp added in the MR job config as well, in order to be able to group one run of a pig script together.
> This field in the job conf for each of the generated Hadoop MR jobs would then be the same for one run and represent when the pig script was started.
