Mkdir doesn't fail if the parent directory doesn't exist on 1.2.0.

I am not talking about parent director. I am talking about the target directory
that you are creating.
In 2.0 where mkdir -p is supported, if you run
{{mkdir -p /path/dir}} and /path/dir already exists, mkdir -p will not fail.
So in 1.2, if you do:
{{mkdir -p /path/dir}} and /path/dir already exists, mkdir will fail. That is
the main difference which makes ignoring -p on 1.2 not an option.

> Per HADOOP-8551 let's port the mkdir -p option to branch-1 for a 1.x release
> to help users transition to the new shell behavior. In Hadoop 2.x mkdir
> currently requires the -p option to create parent directories but a program
> that specifies it won't work on 1.x since it doesn't support this option.
