      Javadoc and pig tutorial

      Description

      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.
