As part of Spark's move to Apache, we have now made this Google Group read-only. To keep receiving updates or asking questions about Spark, please subscribe to us...@spark.incubator.apache.org. You can do this by emailing user-su...@spark.incubator.apache.org. If you prefer a web-based interface for the new list, Nabble provides one at http://apache-spark-user-list.1001560.n3.nabble.com, which allows both viewing old topics and posting new ones from your browser.
Thanks for your patience with this move!
