Odd error -- thinks UDF is referring to a group...

[Jonathan Coveney <jc...@gmail.com>]

I have a jar with UDFS called squeal.jar...I know it works, because I can
access methods in the jar. However, when I try this:

register /home/jcoveney/udfs/squeal/jar/squeal.jar;
A = LOAD 'test.txt' AS (uid:chararray, ss2k:int, t1:chararray, t2:chararray,
t3:chararray);
B = GROUP A BY uid;
C = FOREACH B {
ord = ORDER A BY ss2k ASC;
GENERATE group, FLATTEN(squeal.sessionize((ord.ss2k, ord.t1, ord.t2,
ord.t3),1));
}
DUMP C;

I get this error:

2011-02-28 11:13:26,430 [main] ERROR org.apache.pig.tools.grunt.Grunt -
ERROR 1000: Error during parsing. Invalid alias: squeal in {group:
chararray,A: {uid: chararray,ss2k: int,t1: chararray,t2: chararray,t3:
chararray}}

I'm very confused as to why this is the case....I've used this UDF
successfully in the past. Any clue how to fix this? I appreciate the help.

I am using the most recent trunk.

What is the complete class name of sessionize?
