Doug Cutting updated HADOOP-2528:
---------------------------------
Attachment: HADOOP-2528-0.patch
Here's a candidate patch for this issue.
This also adds generic permission checking methods to FileSystem. Is this the
best place for these? Do they look correct to folks? Should we also use these
utilities within HDFS to check permissions?
Note that it also adds some missing listStatus() methods to FileSystem.java,
required to efficiently implement permission checking, and deprecates more
listPaths() methods.
Finally, we should replace the FileSystem#globPaths methods with
FileSystem#$globStatus() methods, no?
> check permissions for job inputs and outputs
