Hello everyone, I'm trying to run Flink on AWS EMR following the guides from Flink doc <https://ci.apache.org/projects/flink/flink-docs-master/ops/deployment/yarn_setup.html#run-a-single-flink-job-on-hadoop-yarn> and from AWS <https://docs.aws.amazon.com/emr/latest/ReleaseGuide/flink-configure.html> , and it looks like the EMR master is never used, neither for JM nor TM. "bin/yarn-session.sh -q" only shows the core nodes. We are only running Flink on that EMR, so it is wasting of resources.
So, is there any way to use the master node for the job, at least for the JM only? If that is not possible, should I have different hardware configurations between the master node and core nodes (smaller server for the master)? Thanks and best regards, Averell -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
