[jira] Commented: (PIG-191) The resulted files are empty when BinaryStorage optimization is used

["Arun C Murthy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12586177#action_12586177 ] 

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?

> 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}
