Daniel Dai commented on PIG-3251:
---------------------------------
bq. Or, are you suggesting I create two silly wrappers instead of one?
No need, if there is no easy way then forget about it.
> Bzip2TextInputFormat requires double the memory of maximum record size

> 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.
