------------------------------
Summary: Tuple field mangled during flattening
Key: PIG-2717
URL: https://issues.apache.org/jira/browse/PIG-2717
Project: Pig
Issue Type: Bug
Affects Versions: 0.10.0, 0.9.2
Environment: RHEL5 (Linux 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54
EDT 2009 i686 i686 i386 GNU/Linux)
Reporter: Brian Tan
1.txt:
1, 2, 3
4, 5, 6
7, 8, 9
a = load '1.txt' using PigStorage(',') as (x:int, y:int, z:int);
b = foreach a generate TOTUPLE(x, y) as t, z;
c = group b by t;
d = foreach c generate flatten(b);
e = foreach d generate t;
Describing d shows the schema as d: {b::t: (x: int,y: int),b::z: int}
However, when dumping d the output is
(1,3)
(4,6)
(7,9)
Describing e shows the schema as e: {b::t: (x: int,y: int)}
However, when dumping I got the following error:
java.lang.ClassCastException: java.lang.Integer cannot be cast to
org.apache.pig.data.Tuple
