------------------------------------------------------------
Yup, it's just the {{getPos()}} that messes up. Data is still correctly
appended to the end of the file (if you comment out the failing assert, the
test succeeds).

> If you call {{getPos()}} on an {{FSDataOutputStream}} returned by
> {{WebHdfsFileSystem#append}}, it will initially return 0, even if the file
> already had content. This method should return the initial length of the file
> before appending.
