If you intend to run Hadoop mapReduce and Spark on the same cluster concurrently, and you have enough memory on the jobtracker master, then you can run the Spark master (for standalone as Raymond mentions) on the same node . This is not necessary but more for convenience so you only have so ssh into one master (usually id put hive/shark server, spark master, etc on same node).— Sent from Mailbox for iPhone
