> It would be nice if libhdfs exposed mkdirs2.  This version of mkdirs is much more verbose
about any errors that occur-- it throws AccessControlException, FileAlreadyExists, FileNotFoundException,
ParentNotDirectoryException, etc.
> The original mkdirs just throws IOException if anything goes wrong.
> For something like fuse_dfs, it is very important to return the correct errno code when
an error has occurred.  mkdirs2 would allow us to do that.
> I'm not sure if we should just change hdfsMkdirs to use mkdirs2, or add an hdfsMkdirs2.
 Probably the latter, but the former course would maintain "bug compatibility" with ancient
releases-- if that is important.
