-------------------------------------
[~keith.wyss], Thanks for opening this jira. I have seen people often getting
confused because of this. Can you review the patch?
> Top UDF documentation indicates improper use
> --------------------------------------------
>
> Key: PIG-3405
> URL: https://issues.apache.org/jira/browse/PIG-3405
> Project: Pig
> Issue Type: Bug
> Components: documentation
> Affects Versions: 0.10.0
> Environment: Javadoc and pig tutorial
> Reporter: Keith Wyss
> Priority: Minor
> Attachments: PIG-3405.patch
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The documentation in both the source code javadoc:
> http://svn.apache.org/repos/asf/pig/trunk/src/org/apache/pig/builtin/TOP.java
> and the Apache Pig Reference manual:
> http://pig.apache.org/docs/r0.8.1/piglatin_ref2.html#TOP indicates that the
> index that is passed to the TOP UDF should be 1-indexed.
> Reading the code and testing the results, this is false. Zero-indexing gives
> the correct behavior. Users should not be betrayed by the official
> documentation.
