Jacob Perkins updated PIG-3779:
-------------------------------
Status: Open (was: Patch Available)
> 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
> Assignee: 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}
