> hadoop dfs -test doesn't act like its shell equivalent, making it difficult to actually
use if you are used to the real test command:
> hadoop:
> $hadoop dfs -test -d /nonexist; echo $?
> test: File does not exist: /nonexist
> 255
> shell:
> $ test -d /nonexist; echo $?
> 1
> a) Why is it spitting out a message? Even so, why is it saying file instead of directory
when I used -d?
> b) Why is the return code 255? I realize this is documented as '0' if true.  But docs
basically say the value is undefined if it isn't.
> c) where is -f?
> d) Why is empty -z instead of -s ?  Was it a misunderstanding of the man page?
