Description

When creating a hadoop archive and specifying an output path of an already existing file, we get an "Invalid Output" error message.

[schu@hdfs-vanilla-1 ~]$ hadoop archive -archiveName foo.har -p /user/schu testDir1 /user/schu
Invalid Output: /user/schu/foo.har

This error can be improved to tell users immediately that the output path already exists.
