Wendy Chien updated HADOOP-281:
-------------------------------
Attachment: addNode.patch
TestDFSMkdirs.java
Hi Arun,
I was simultaneously working on this bug and had a different fix. Hairong and
I think it would be simpler to check the path/parent is a directory in addNode
(which is called by unprotectedMkdir which in turn is called by mkdirs). I
think the check in addNode is required regardless of mkdirs.
I have attached my patch file along with test code for the change.
Please look at it and let me know what you think.
Thanks,
Wendy
