Cheng Lian d36c5fca7b [SPARK-6608] [SQL] Makes DataFrame.rdd a lazy val ... Before 1.3.0, `SchemaRDD.id` works as a unique identifier of each `SchemaRDD`. In 1.3.0, unlike `SchemaRDD`, `DataFrame` is no longer an RDD, and `DataFrame.rdd` is actually a function which always returns a new RDD instance. Making `DataFrame.rdd` a lazy val should bring the unique identifier back. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/apache/spark/5265) <!-- Reviewable:end --> Author: Cheng Lian <lian@databricks.com> Closes #5265 from liancheng/spark-6608 and squashes the following commits: 7500968 [Cheng Lian] Updates javadoc 7f37d21 [Cheng Lian] Makes DataFrame.rdd a lazy val		2015-04-01 21:34:45 +08:00
