Jian He commented on YARN-6533:
-------------------------------
In SliderAppMaster
Below code also didn't replace '_' with '-'. Is it required to replace '_' with
'-' for the YARN_ID ? what's the expectation ?
{code}
serviceRecord.set(YarnRegistryAttributes.YARN_ID, appId.toString());
{code}
> Race condition in writing service record to registry in yarn native services

> 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.
