----------------------------------
Thanks Colin and Chris.
Bq. Let's create JIRAs to use the JDK7 APIs when they become available to us.
Good idea! I created HADOOP-9590 and documented all problems we run into w.r.t.
file operations on JDK6. Feel free to add to the Jira if I missed something.
> add NativeIO#mkdirs, that provides an error message on failure

> It would be nice to have a variant of mkdirs that provided an error message

> unit tests that rely on mkdir / mkdirs-- the ChecksumFilesystem tests, for
> example.
