2 possible future improvements that we can do within this Jira or in a future
jira:
* For each resource to create the symlink we try to create the directory. We
should move the creation of the directory in ContainerExecutor.
* If the symlink failed we still start the container and we crash afterward. We
have to avoid to start the container.

[^HADOOP-15528-HADOOP-15461.v3.patch] is changing the way containers are
launched.
I'm not sure this is OK.
[~jlowe], [[email protected]], what are your thoughts on this?
I would be inclined towards keeping the old semantic.

> {{ContainerLaunch}} currently uses its own utility to create links (including
> winutils).
> This should be deprecated and rely on {{FileUtil#SymLink}} which is already
> multi-platform and pure Java.
