Tao Wang created FLINK-5903:
-------------------------------

             Summary: taskmanager.numberOfTaskSlots and yarn.containers.vcores did not work well in YARN mode
                 Key: FLINK-5903
                 URL: https://issues.apache.org/jira/browse/FLINK-5903
             Project: Flink
          Issue Type: Bug
          Components: YARN
            Reporter: Tao Wang


Now Flink did not respect taskmanager.numberOfTaskSlots and yarn.containers.vcores in flink-conf.yaml, but only -s parameter in CLI.

Details is that taskmanager.numberOfTaskSlots is not working in anyway andyarn.containers.vcores is only used in requesting container(TM) resources but not aware to TM, which means TM will always think it has default(1) Slots if -s is not configured.
