Richard Ding commented on PIG-864:
----------------------------------
The plan is to add a new entry--"pig.parent.jobid"--to each job which has
parents, in addition to log the job DAG of a Pig script to the Pig log.
> Record graph of execution of Map-Reduce jobs executed by a Pig script
> ---------------------------------------------------------------------

> It would be useful for offline analysis if Pig were to record the entire
> graph of Map-Reduce jobs executed by a singe Pig script.
> For starters a simple 'parent jobid' for each MR job in the graph would be
> nice.
