> FileSystem#createNonRecursive() is deprecated.
> However, there is no DistributedFileSystem#create() implementation which throws exception if parent directory doesn't exist.
> This limits clients' migration away from the deprecated method.
> For HBase, IO fencing relies on the behavior of FileSystem#createNonRecursive().
> Variant of create() method should be added which throws exception if parent directory doesn't exist.
