>                 URL: https://issues.apache.org/jira/browse/FLINK-16025
>             Project: Flink
>          Issue Type: Bug
>          Components: Deployment / Kubernetes
>    Affects Versions: 1.10.0
>            Reporter: Canbin Zheng
>            Priority: Critical
>             Fix For: 1.10.1, 1.11.0

> The Service would always expose 6124 port if it should expose that port, and while building ServicePort we do not explicitly specify a target port, so the target port would always be 6124 too.
> {code:java}
> // From ServiceDecorator.java
> servicePorts.add(getServicePort(
>  getPortName(BlobServerOptions.PORT.key()),
>  Constants.BLOB_SERVER_PORT));
> private ServicePort getServicePort(String name, int port) {
>    return new ServicePortBuilder()
>       .withName(name)
>       .withPort(port)
>       .build();
> }
> {code}
>  
> meanwhile, the Container of the JM would expose the blob server port which is configured in the Flink Configuration,
> {code:java}
> // From FlinkMasterDeploymentDecorator.java
> final int blobServerPort = KubernetesUtils.parsePort(flinkConfig, BlobServerOptions.PORT);
> ...
> final Container container = createJobManagerContainer(flinkConfig, mainClass, hasLogback, hasLog4j, blobServerPort);
> {code}
>  
> so there is a risk that in non-HA mode the TM could not execute Task due to dependencies fetching failure if the Service exposes a blob server port which is different from the JM Container when one configures the blob server port with a value different from 6124.
