Billie Rinaldi updated YARN-6533:
---------------------------------
Attachment: YARN-6533-yarn-native-services.001.patch
This patch does not write the initial ServiceRecord (without the IP) in the
case of the Docker provider, to prevent this initial registration from
asynchronously occurring after the ServiceRecord with the IP is written. It
also logs and retries the writing of the ServiceRecord containing the IP if an
IOException is thrown, instead of just logging the exception.
> 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.
