 Logical to Physical Plan Translation fails when temporary alias are created 
 within foreach
 --

 Key: PIG-747
 URL: https://issues.apache.org/jira/browse/PIG-747
 Project: Pig
  Issue Type: Bug
Affects Versions: 0.4.0
Reporter: Viraj Bhat
Assignee: Alan Gates
 Fix For: 0.9.0

 Attachments: physicalplan.txt, physicalplanprob.pig, PIG-747-1.patch


 Consider a the pig script which calculates a new column F inside the foreach 
 as:
 {code}
 A = load 'physicalplan.txt' as (col1,col2,col3);
 B = foreach A {
D = col1/col2;
E = col3/col2;
F = E - (D*D);
generate
F as newcol;
 };
 dump B;
 {code}
 This gives the following error:
