Review Comment:
With head optimization enabled and read footer optimization enabled, the
abfsInputStream is not aware of the contentLength and hence, it would only read
data for which the range is provided. With the first remote call done, the
inputStream will get aware of the contentLength and would be able to use it for
further reads.
