             Summary: Flex'ing with unknown role name results in BadConfigException
                 Key: SLIDER-274
                 URL: https://issues.apache.org/jira/browse/SLIDER-274
             Project: Slider
          Issue Type: Bug
            Reporter: Ted Yu


I used 'slider flex' command with unknown role name - 'worker'
I got the following exception:
{code}
org.apache.hadoop.ipc.RemoteException(org.apache.slider.core.exceptions.BadConfigException): Missing option yarn.role.priority
	at org.apache.slider.core.conf.MapOperations.getMandatoryOption(MapOperations.java:92)
	at org.apache.slider.server.appmaster.state.AppState.createDynamicProviderRole(AppState.java:559)
	at org.apache.slider.server.appmaster.state.AppState.buildRoleRequirementsFromResources(AppState.java:669)
	at org.apache.slider.server.appmaster.state.AppState.updateResourceDefinitions(AppState.java:631)
	at org.apache.slider.server.appmaster.SliderAppMaster.flexCluster(SliderAppMaster.java:1090)
	at org.apache.slider.server.appmaster.SliderAppMaster.flexCluster(SliderAppMaster.java:1209)
	at org.apache.slider.server.appmaster.rpc.SliderClusterProtocolPBImpl.flexCluster(SliderClusterProtocolPBImpl.java:68)
	at org.apache.slider.api.proto.SliderClusterAPI$SliderClusterProtocolPB$2.callBlockingMethod(SliderClusterAPI.java:262)
{code}
However, this resulted in the addition of following section to /user/yarn/.slider/cluster/cl4/resources.json:
{code}
    "worker" : {
      "yarn.component.instances" : "1"
    }
{code}
This means that subsequent flex commands would always fail because of the above section which doesn't have yarn.role.priority
