Service could expose blob server port mismatched with JM Container

    Details

      Description

      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.

      // 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();
      }
      
      
      

       

      meanwhile, the Container of the JM would expose the blob server port which is configured in the Flink Configuration,

      // From FlinkMasterDeploymentDecorator.java
      
      final int blobServerPort = KubernetesUtils.parsePort(flinkConfig, BlobServerOptions.PORT);
      
      ...
      
      final Container container = createJobManagerContainer(flinkConfig, mainClass, hasLogback, hasLog4j, blobServerPort);
      

       

      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.
