> While looking at user's OOM heap dump, noticed that pig's Bzip2TextInputFormat consumes memory at both
> Bzip2TextInputFormat.buffer (ByteArrayOutputStream)
> and actual Text that is returned as line.
> For example, when having one record with 160MBytes, buffer was 268MBytes and Text was 160MBytes.
> We can probably eliminate one of them.
