Giovanni Matteo Fumarola commented on HADOOP-15528:
---------------------------------------------------

[~jlowe] thanks for the comment.
You have a good point. I am going to add a boolean configuration to enable the execution of
symlink from NM or fallback to the batch script.

> {{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.
