unix - Permission Denied error setting 777 folder access -


i created user admin access named hadoop. funny thing when create folder , try give 777 access gives me error.

hadoop@linux:~$ mkdir testfolder hadoop@linux:~$ ls -ltra testfolder/ total 8 drwxrwxrwx 25 hadoop sudo   4096 jun 14 20:00 .. drwxrwxr-x  2 hadoop hadoop 4096 jun 14 20:00 . hadoop@linux:~$ chmod -777 -r testfolder/ chmod: cannot read directory ‘testfolder/’: permission denied

why when creator of directory ? 

hadoop@linux:~$ groups  hadoop root sudo

strangely, using gui, can go in , right click directory , change file permissions. can me understand not understanding.

note : use ubuntu 14

your command chmod -777 -r testfolder/ issue here, more specific - part of first argument.

leave away, use chmod 777 -r testfolder/ , should fine...

not sure details, -777 should remove permissions, preventing access @ least recursive portion of command. assume not want do. instead want grant more permissions directory. looks command blocks itself. though might purpose, @ least in indirect manner.
