Rohini Palaniswamy commented on PIG-3251:
-----------------------------------------
Just noticed one more issue. -Dppig.bzip.use.hadoop.inputformat in one of the
e2e tests has ppig instead of pig.
Can we also do
- mLog.info instead of mLog.debug . It is just going to appear once or twice
in the front-end and backend. So info should be fine and would be useful.
- Add one line documentation in pig.properties
> 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.
