             Summary: Assert constructs ConstantExpression with null when no comment is given
                 Key: PIG-3779
                 URL: https://issues.apache.org/jira/browse/PIG-3779
             Project: Pig
          Issue Type: Bug
            Reporter: Cheolsoo Park
             Fix For: 0.13.0


I ran into this problem with Lipstick after deploying ASSERT. When ASSERT is not given any comment, LogicalPlanBuilder constructs ConstantExpression with null. Later tools like Lipstick try to convert it to a String resulting in NPE.

Although it's possible to handle this case in Lipstick, I feel ConstantExpression shouldn't be constructed with null in the first place.

Here is the code in LogicalPlanBuilder-
{code}
ConstantExpression constExpr = new ConstantExpression(exprPlan, comment);
{code}
