[jira] [Created] (PIG-3405) Top UDF documentation indicates improper use

Keith Wyss created PIG-3405:
-------------------------------

             Summary: 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


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.
