Description

When the user doesn't have access permission to the local directory, the "hadoop fs -put" command prints a confusing error message "No such file or directory".

$ whoami
systest
$ cd /home/systest
$ ls -ld .
drwx------. 4 systest systest 4096 Jan 13 14:21 .
$ mkdir d1
$ sudo -u hdfs hadoop fs -put d1 /tmp
put: `d1': No such file or directory

It will be more informative if the message is:

put: d1 (Permission denied)

If the source is a local file, the error message is ok:

put: f1 (Permission denied)
