schema inferred incorrectly
---------------------------
Key: PIG-592
URL: https://issues.apache.org/jira/browse/PIG-592
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Christopher Olston
A simple pig script, that never introduces any schema information:
A = load 'foo';
B = foreach (group A by $8) generate group, COUNT($1);
C = load 'bar'; // ('bar' has two columns)
D = join B by $0, C by $0;
E = foreach D generate $0, $1, $3;
Fails, complaining that $3 does not exist:
java.io.IOException: Out of bound access. Trying to access non-existent column:
3. Schema {ID2::group: bytearray,long,bytearray} has 3 column(s).
Apparently Pig gets confused, and thinks it knows the schema for C (a single
bytearray column).
