---------------------------------------

             Summary: Sample and Limit should also defer input evaluation under codegen
                 Key: SPARK-22124
                 URL: https://issues.apache.org/jira/browse/SPARK-22124
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: Liang-Chi Hsieh
            Priority: Minor


We can override {{usedInputs}} to claim that an operator defers input evaluation. {{Sample}} and {{Limit}} are two operators which should claim it but don't. We should do it.
