             Summary: Can't join describe() of DataFrame in Scala 2.10
                 Key: SPARK-16173
                 URL: https://issues.apache.org/jira/browse/SPARK-16173
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.6.1, 1.5.2, 2.0.0
            Reporter: Davies Liu


descripbe() of DataFrame use Seq() (it's a Iterator actually) to create another DataFrame, which can not be serialized in Scala 2.10.
