Steve Loughran commented on HADOOP-12667:
-----------------------------------------
hadoop already has some atomicity problems with create-no-overwrite, given the
write doesn't even happen until the close() call. But...createNonRecursive is
potentially useful, as it will fail-fast if the parent doesn't exist.
Looking at the patch, I can see we need the filesystem spec updated with
coverage of the reinstated method, ideally with a recommended IOE subclass
{{FileNotFoundException}} if the parent isn't there...then we can add this test
here to the contract tests and roll it out across all the filesystems.
Sean: fancy taking that on?
