I am using a MapR (YARN) cluster with 3 nodes. I am trying to deploy 6 Samza jobs on the cluster for some processing on data streams. All jobs are correct. I tried deploying 2-3 in parallel and they work. However when I deploy all the 6 Samza jobs in parallel I see following logs. The tasks continue to run and dont produce expected output data stream.
The status of the nodes on my ResourceManager web dashboard is as follows-
Can anyone suggest how can this be resolved. I think that maybe the application does not have sufficient resources to run all of them in parallel. What change can I try?
