Sumit Mohanty updated SLIDER-274:
---------------------------------
Sprint: Slider October #2
> 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
> Assignee: Steve Loughran
> Fix For: Slider 0.50
>
>
> 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)

> 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
