Description

New logical plan is failing following code:
<pre>
A = load 'data' AS (query:chararray, type:chararray, freq:int);
B = group A by query;

C = foreach B {

click = filter A by (type == 'c');
pv = filter A by (type == 'p');
click_sum = (IsEmpty(click.freq)? 0 : SUM(click.freq));

generate
COUNT(click),
COUNT(pv),
click_sum;
}
store C into 'C';
</pre>
