Description

Looked at

junit.framework.AssertionFailedError
    at org.apache.pig.test.TestTypedMap.testOrderBy(TestTypedMap.java:352)

This looks like a valid test case failing with incorrect result.

% cat test/orderby.txt
[key#1,key9#23]
[key#3,key3#2]
[key#22]

% cat test/orderby.pig
a = load 'test/orderby.txt' as (m:[]);
b = foreach a generate m#'key' as b0;
dump b;
c = order b by b0;
dump c;

% java ... org.apache.pig.Main    -x local test/orderby.pig 
[dump b]
(1)
(3)
(22)

...
[dump c]
(1)
(1)
(22)
%

where did the '(3)' go?
