The paper you mention references a Spark-based LU decomposition approach. AFAIK there is no current implementation in Spark but there is a JIRA open (https://issues.apache.org/jira/browse/SPARK-8514 <https://issues.apache.org/jira/browse/SPARK-8514>) that covers this - seems to have gone quiet though. ------------------------------------------------------------------------------- Robin East Spark GraphX in Action Michael Malak and Robin East Manning Publications Co. http://www.manning.com/books/spark-graphx-in-action <http://www.manning.com/books/spark-graphx-in-action>
