GitHub user dongjoon-hyun opened a pull request: https://github.com/apache/spark/pull/13900 [SPARK-16173][SQL] Can't join describe() of DataFrame in Scala 2.10 ## What changes were proposed in this pull request? This PR fixes `DataFrame.describe()` by forcing materialization to make the `Seq` serializable. Currently, `describe()` of DataFrame throws `Task not serializable` Spark exceptions when joining in Scala 2.10. ## How was this patch tested? Manual. (After building with Scala 2.10, test on `bin/spark-shell` and `bin/pyspark`.)
