Daniel Dai commented on PIG-3251:
---------------------------------
Hi, [~knoguchi], is the patch ready? Some comments for pig-3251-trunk-v04.patch:
1. Cache job in PigStorage seems to be confusing, can we just cache splittable?
2. Is it possible to wrap a codec deal with both bz2/bz? Just feel it might be
less confusing than wrap bz2 alone, and use PigTextInputFormat for bz
> 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.
