Hi, I was wondering if
a. there's a more detailed example of how you specify a workflow for Oozie to run than http://oozie.apache.org/docs/4.1.0/DG_Examples.html. I'm not seeing the code there that tells it where the workflow definition is. b. there's a way in Oozie to feed it a dynamically (programmatically) generated workflow definition rather than something prepared ahead of time. c. how does Oozie know where to run a given task/action? E.g. here http://oozie.apache.org/docs/4.1.0/WorkflowFunctionalSpec.html#Appendix_B_Workflow_Examples - what controls where a given task is executed? Is it the Job Tracker? I'm wondering if there's a way to autoscale up or down the cluster nodes if the workflow engine is getting less load or more load i.e. work load peaks and valleys.. Thanks.
