> 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
