------------------------------------
Summary: Allow custom hostname for docker containers in native
services
Key: YARN-6804
URL: https://issues.apache.org/jira/browse/YARN-6804
Project: Hadoop YARN
Issue Type: Sub-task
Components: yarn-native-services
Reporter: Billie Rinaldi
Assignee: Billie Rinaldi
Fix For: yarn-native-services
Instead of the default random docker container hostname, we could set a more
user-friendly hostname for the container. The default could be a hostname based
on the container ID, with an option for the AM to provide a different hostname.
In the case of the native services AM, we could provide the hostname that would
be created by the registry DNS server. Regardless of whether or not registry
DNS is enabled, this would be a more useful hostname for the docker container.
