Steve Loughran commented on HADOOP-12718:
-----------------------------------------
# There's a {{PathAccessDeniedException}} in Hadoop, not sure if its the one to
use or not...my IDE isn't showing much (any?) use of that exception. Given it's
obscurity, I'd stick with what the patch has: the java.nio one. (Looking at
HADOOP-13130 I See that I'd just picked it up...I'll go to
{{java.nio.AccessDeniedException}} there.
I think to tighten the specification properly you're going to have follow the
full process
# look at what HDFS does. write a test for this if needed
# Look at what the other filesystems do, such as azure, webHDFS. Ignore S3A,
I'm setting that up right now.
# If any of the others return null, they'll need to be fixed.
# then we should consider having a permissions test. This is trickier than it
looks, as permissions is where things vary, and setting them can be hard to do
in a cross-platform, cross-FS way.
Finally, I'd make the FS requirement, {{throws AccessDeniedException,
IOException}} so that it is considered acceptable to raise other exceptions.
This will avoid having to fix every other FS so that it is consistent with this
tightening of the spec.
