The populateDAG function is invoked before it is submitted to YARN. So the
app id not assigned yet.
Hi guys - when I try to retrieve the application id with:
("{ApplicationId=" + dag.getValue(Context.DAGContext.APPLICATION_ID) +
"}\n”) the applicationId is reported as null.I’m trying to run this inside of the “populateDAG” function. Am I doing something wrong?
