----------------------------------------
Related:
PIG-2658 (Add start time for pig script in generated Map-Reduce job conf )
PIG-2587 (Add logical plan signature to the job conf)
I think those two are better implementations of workflow id and workflow name
(assuming multiple versions of the same workflow don't start at the same exact
time).
Adding the adjacent nodes info is interesting. I am not sure we produce
something equivalent right now.. Bill Graham would know.

> Adding workflow properties to the job configuration would enable logging and
> analysis of workflows in addition to individual MapReduce jobs. Suggested
> properties include a workflow ID, workflow name, adjacency list connecting
> nodes in the workflow, and the name of the current node in the workflow.
> mapreduce.workflow.id - a unique ID for the workflow, ideally prepended with
> the application name
> e.g. pig_<pigScriptId>
> mapreduce.workflow.name - a name for the workflow, to distinguish this
> workflow from other workflows and to group different runs of the same workflow
> e.g. pig command line
> mapreduce.workflow.adjacency - an adjacency list for the workflow graph,
> encoded as mapreduce.workflow.adjacency.<source node> = <comma-separated list
> of target nodes>
> mapreduce.workflow.node.name - the name of the node corresponding to this
> MapReduce job in the workflow adjacency list
