             Summary: Add start time for pig script in generated Map-Reduce job 
conf
                 Key: PIG-2658
                 URL: https://issues.apache.org/jira/browse/PIG-2658
             Project: Pig
          Issue Type: Improvement
            Reporter: Joep Rottinghuis


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.
