["Brock Noland (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-4239?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14230863#comment-14230863 ] 

Brock Noland commented on PIG-4239:
-----------------------------------

Patch looks good to me! Nice work!

{noformat}
            storeJobConf.set("mapred.output.dir", poStore.getSFile()
	                    .getFileName());
{noformat}

I think we should use the {{FileOutputFormat.set*}} method here..

> If "pig.output.lazy" is "true", empty part files from the output will be omitted.
> steps to reproduce
> 1. set "pig.output.lazy" as “true" in $PIG_HOME/conf/pig.properties.
> 2. run following lazy.pig script in spark mode:
> cat lazy.pig
> a = load '/user/pig/lazy' using PigStorage();
> b = filter a by $0  == 'hey';
> c = store b into '/tmp/lazy.out';
> lazy.pig and lazy are attached
> 3.  empty file "/tmp/lazy.out/part-rxxxx” is still generated, the empty file is expected not to be generated when "pig.output.lazy" is "true"
