Jason Lowe commented on HADOOP-15528:
-------------------------------------
It may be useful to have a config disable for this given it could cause
difficulties, but it'd also be nice if we could avoid users shooting themselves
in the foot with this config. If we know using this config with some container
executors makes no sense then it'd be nice to either fail fast on NM startup,
warn it's being ignored, or otherwise do something smarter than just failing
every container execution in a difficult to debug manner.

> {{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.
