> Currently RandomSampleLoader calls skip() on the underlying input stream
> (BufferedPositionedInputStream) in its getNext(). The input stream may not
> actually skip over the amount the RandomSampleLoader needs in one call.
> RandomSampleLoader should check the return value from the skip() call and
> ensure that skip() is called repeatedly (if necessary) till the needed number
> of bytes are skipped.
