Review comment:
getPos() will return contentlength post a read to (incl) EOF; however,
seek/skip to invalid position is not supported, so getPos after any of these
ops will return valid position

> Modify AbfsInputStream seek method to throw EOF exception on seek to
> contentLength for a non-empty file. With this change, it will no longer be
> possible for the inputstream position (as obtained by getPos() API) to be
> moved to contentlength manually, except post reading the last byte.
