Hi, We are using EMR and using oozie right now to deploy streaming job (Workflow). I just want to know best practice to deploy streaming job. (In mesos we deploy using marathon, but what should be best approach in yarn which enforce only once instance and restart if it fails for any reason)
I noticed sometime not sure yarn launched two instance of streaming job, It seems to me if driver is unhealthy then its try to second attempt and in the meantime old driver recovers (That why need to check how we enforced only one instance of streaming is running on yarn) -Saurabh
