             Summary: Add a yarn session parameter for the number of task slots per task manager
                 Key: FLINK-968
                 URL: https://issues.apache.org/jira/browse/FLINK-968
             Project: Flink
          Issue Type: Improvement
            Reporter: Stephan Ewen
            Assignee: Robert Metzger
            Priority: Critical


In order to have a transparent and elegant YARN setup, the shell needs a parameter to specify how many task slots each task manager should offer.

If that flag is not specified, then each taskmanager will offer as many slots as the JVM determines system cores. We may think about changing that to a default of one, to make it more predictable.
