-------------------------------------
[~shaneku...@gmail.com] Thanks for pointing out the issue.
{quote}As a result, the "source" of the mounts added in {{AbstractLauncher}}
are all relative paths. These need to be specified as absolute paths in the
final mount that is added to the {{docker run}} command
{quote}
I think it may be better not to get rid of
{{YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS}} at this point because
{{AbstractLauncher}} in Yarn service while creating the {{LaunchContext}}
doesn't know about the absolute path of the localized resource.
I can put a simple fix to merge user specified
{{YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS}} with the once computed
by yarn service.
Let me know your thoughts?

> Existing YARN native service overwrites

> Following logic overwrites the

> {code:java}
> StringBuilder sb = new StringBuilder();

> if (sb.length() > 0) {
> sb.append(",");

> sb.append(mount.getKey());
