      Description

      If you try to use hadoop-aws with Beam to read from AWS S3 it breaks because S3AInputStream (the implementation of Hadoop's FSDataInputStream) is not ByteBufferReadable.

      Exception in thread "main" java.lang.UnsupportedOperationException: Byte-buffer read unsupported by input stream
