Doug Cutting updated HADOOP-2528:
---------------------------------
Attachment: HADOOP-2528-1.patch
Here's an updated version of the patch.
I previously assumed that one could, e.g., read a file you own with --------rwx
permissions, but in fact you can't. If you're the owner, then only the owner
permissions are examined. I've updated the generic checker here to reflect
that. I learn something new every day!
