Arun C Murthy commented on PIG-191:
-----------------------------------
Xu, the empty files are the outputs of the reduces - however results_39/ should
contain one or more map-* files which contain the actual outputs. (The reduce-*
files will be empty).
Is that what you see here?
> The resulted files are empty when BinaryStorage optimization is used

> Project: Pig
> Issue Type: Bug
> Reporter: Xu Zhang
> Assignee: Arun C Murthy
> Attachments: BinaryReadWrite.pl

>
> With the following Pig script, I would expect results_39 to contain the
> binary content of PigLoggingTest, but actually results_39 contains several
> empty files. BinaryReadWrite.pl in this case simply reads in the binary file
> PigLoggingTest from STDIN and then output to STDOUT in binary.
> {code}
> A = load '/user/xu/test/PigLoggingTest' split by 'file';
> B = stream A through `BinaryReadWrite.pl -o t`;
> store B into 'results_39';
> {code}
