------------------------------------

             Summary: Race condition in writing service record to registry in yarn native
services
                 Key: YARN-6533
                 URL: https://issues.apache.org/jira/browse/YARN-6533
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Billie Rinaldi
            Assignee: Billie Rinaldi


The ServiceRecord is written twice, once when the container is initially registered and again
in the Docker provider once the IP has been obtained for the container. These occur asynchronously,
so the more important record (the one with the IP) can be overwritten by the initial record.
Only one record needs to be written, so we can stop writing the initial record when the Docker
provider is being used.
