Subject [jira] Commented: (PIG-202) ComparatorFunc provided to ORDER clause is not always honoured
Date Mon, 28 Apr 2008 12:18:55 GMT

    [ https://issues.apache.org/jira/browse/PIG-202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12592796#action_12592796
] 

Pi Song commented on PIG-202:
-----------------------------

1) The first quantile always being zero is something really has to be fixed.
2) The <= to < thing also helps a (very tiny) bit more to make the first bucket the
same size as others. 

Theoretically, there should be some small performance gain due to (1)

I'm looking forward to seeing the result!!!

> Specifying a comparator function is acknowledge neither by local implementation, nor
by quartile lookup job.
> Patch coming soon.
