> MapJoinTableContainerSerDe currently hard-codes the buffer sizes as 4K.  If we remove
the explicit buffer size, it will fall back to using the customized buffer size (or 4K):
> {code}
>    public FSDataInputStream open(Path f) throws IOException {
>      return open(f, getConf().getInt("io.file.buffer.size", 4096));
>    }
> {code}
