Re: Spark-on-YARN architecture
I suppose you just provision enough resource to run both on that node... but it really shouldn't matter. The RM and your AM aren't communicating heavily.

Re: Spark-on-YARN architecture
Thanks for the quick reply. I am running the application in YARN client mode. And I want to run the AM on the same node as RM inorder use the node which otherwise would run AM. How can I get AM run on the same node as RM? On Tue, Mar 10, 2015 at 3:49 PM, Sean Owen wrote: > In YARN cluster mode, there is no Spark master, since YARN is your > resource manager.

Re: Spark-on-YARN architecture
In YARN cluster mode, there is no Spark master, since YARN is your resource manager. Yes you could force your AM somehow to run on the same node as the RM, but why -- what do think is faster about that?

Spark-on-YARN architecture
Hi all, I have Spark cluster setup on YARN with 4 nodes(1 master and 3 slaves). When I run an application, YARN chooses, at random, one Application Master from among the slaves. This means that my final computation is being carried only on two slaves. This decreases the performance of the cluster. 1. Is this the correct way of configuration? What is the architecture of Spark on YARN? 2. Is there a way in which I can run Spark master, YARN application master and resource manager on a single node?(so that I can use three other nodes for the computation) Thanks Harika -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Spark-on-YARN-architecture-tp21986.html Sent from the Apache Spark User List mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
