Is this a known pig8->pig9 regression? Scoping within a foreach block
relation = load 'relation' as (val1:int,val2:int,val3:int);
b = load 'temp';
relation2 = FOREACH (GROUP relation BY val1) {
a = COUNT(relation.val2);
b = SUM(relation.val3);
GENERATE group, (long)a, (long)b;
}
in pig 8 this works, in pig 9 it doesn't.
<file regress, line 8, column 33> Invalid scalar projection: b : A column
needs to be projected from a relation for it to be used as a scalar
Details at logfile: /var/log/pig/pig_1320887043189.log
Just wondering if this is a known issue, or if I should make a jira?

Sounds something similar to PIG-2312.

I definitely can work around it (and have :), but given it works
differently in pig8 and pig9, I thought I'd mention it.

looks like (long) b is getting the wrong b.
Make the names different?
