> Each job may contain DAG information, but the log4j appender ignores it for all but the
first job in the workflow.  This is a problem because Pig may generate multiple independent
DAGs for a single script, e.g. if "exec" is called in the middle of the script.  The log4j
appender needs to merge together the DAG information for all the jobs in a workflow instead
of assuming that the DAG won't change.
