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: 0.3.0 Reporter: Viraj Bhat Fix For: 0.3.0 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: ======================================================================================================================================= Caused by: org.apache.pig.backend.hadoop.executionengine.physicalLayer.LogicalToPhysicalTranslatorException: ERROR 2015: Invalid physical operators in the physical plan at org.apache.pig.backend.hadoop.executionengine.physicalLayer.LogToPhyTranslationVisitor.visit(LogToPhyTranslationVisitor.java:377) at org.apache.pig.impl.logicalLayer.LOMultiply.visit(LOMultiply.java:63) at org.apache.pig.impl.logicalLayer.LOMultiply.visit(LOMultiply.java:29) at org.apache.pig.impl.plan.DependencyOrderWalkerWOSeenChk.walk(DependencyOrderWalkerWOSeenChk.java:68) at org.apache.pig.backend.hadoop.executionengine.physicalLayer.LogToPhyTranslationVisitor.visit(LogToPhyTranslationVisitor.java:908) at org.apache.pig.impl.logicalLayer.LOForEach.visit(LOForEach.java:122) at org.apache.pig.impl.logicalLayer.LOForEach.visit(LOForEach.java:41) at org.apache.pig.impl.plan.DependencyOrderWalker.walk(DependencyOrderWalker.java:68) at org.apache.pig.impl.plan.PlanVisitor.visit(PlanVisitor.java:51) at org.apache.pig.backend.hadoop.executionengine.HExecutionEngine.compile(HExecutionEngine.java:246) ... 10 more Caused by: org.apache.pig.impl.plan.PlanException: ERROR 0: Attempt to give operator of type org.apache.pig.backend.hadoop.executionengine.physicalLayer.expressionOperators.Divide multiple outputs.
