Colin Patrick McCabe updated HADOOP-9929:
-----------------------------------------

    Attachment: HADOOP-9929.001.patch

Here's a patch which lets all exceptions except FileNotFound propagate, effectively restoring the old behavior.  This means that, as before, your glob will fail if you encounter permission issues.  It's probably best to keep it this way for compatibility reasons.

I also added a unit test for this.

> Using "hadoop fs -ls" to list a path where the permissions of a parent directory are insufficient ends up reporting "no such file or directory" on the full path rather than reporting the permission issue.  For example:
> {noformat}
> $ hadoop fs -ls /user/abc/tests/data
> ls: `/user/abc/tests/data': No such file or directory
> $ hadoop fs -ls /user/abc
> ls: Permission denied: user=somebody, access=READ_EXECUTE, inode="/user/abc":abc:hdfs:drwx------
> {noformat}
