             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: Matt McCline
            Assignee: Matt McCline
             Fix For: 3.0.0


 
Many vector expression classes are missing guards around setting noNulls among 
other things.

{code:java}
    // Carefully update noNulls...
    if (outputColVector.noNulls) {
      outputColVector.noNulls = inputColVector.noNulls;
    }
 {code}
