    Description

      See file IsNotNull.java in package org.apache.hadoop.hive.ql.exec.vector.expressions

      It never looks at the noNulls flag on the input vector, but accesses the isNull[] array anyway. This can yield incorrect results.

      isRepeating and noNulls are not set in the output, which can also cause wrong results.
