                 Key: SPARK-9784
                 URL: https://issues.apache.org/jira/browse/SPARK-9784

Exchange needs to check whether unsafe mode is enabled in its {{tungstenMode}} method:

{code}

  override def nodeName: String = if (tungstenMode) "TungstenExchange" else "Exchange"

  /**
   * Returns true iff we can support the data type, and we are not doing range partitioning.
   */
  private lazy val tungstenMode: Boolean = {
    GenerateUnsafeProjection.canSupport(child.schema) &&
      !newPartitioning.isInstanceOf[RangePartitioning]
  }
{code}
