> When creating a hadoop archive and specifying an output path of an already existing file,
we get an "Invalid Output" error message.
> {code}
> [schu@hdfs-vanilla-1 ~]$ hadoop archive -archiveName foo.har -p /user/schu testDir1 /user/schu
> Invalid Output: /user/schu/foo.har
> {code}
> This error can be improved to tell users immediately that the output path already exists.
