    [ https://issues.apache.org/jira/browse/PIG-5167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16025723#comment-16025723 ] 

liyunzhang_intel commented on PIG-5167:
---------------------------------------

[~nkollar]: my suggestion is 
1. add a new verify_pig_script to Limit_13
{code}
			{
				'num' => 13,
				'execonly' => 'spark', # Limit_4 failed on Spark: distinct doesn't do implicit sort like it does in MR
				'pig' =>q\a = load ':INPATH:/singlefile/studentnulltab10k';
b = distinct a;
c = limit b 100;
store c into ':OUTPATH:';\,
                 'verify_pig_script' =>q\a = load ':INPATH:/singlefile/studentnulltab10k';
                                       b = distinct a;
                                       c = limit b 100;
                                       store c into ':OUTPATH:';\,
			}
{code}
It is not very good because the script and verify_script are same.
2.  If #option1 is not accepted, remove Limit_13 and leave PIG-5167 open

I have tried #option1 but failed because the verify_pig_script is executed by benchmark mode(mr). so the result is different in spark and mr.
