> Let /foo be a *directory* in HDFS (issue does not occur with files) and /bar be a local
dir. Do something like:
> {code}
> $ chmod u-w /bar
> $ hadoop -get /foo/myfile /bar
> copyToLocal: Permission denied  # correctly tells me permission is denied
> $ hadoop -get /foo /bar
> copyToLocal: null           
> $ hadoop -get /foo/ /bar
> copyToLocal: No such file or directory
> {code}
> I've been banging my head for a bit trying to figure out why hadoop thinks my directory
doesn't exist, but it turns out the problem was just with my local permissions. The "Permission
denied" error would've been a lot nicer to get.
