> 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}
