Re: spark-defaults.conf optimal configuration
Hello Neelesh, Thank you for the checklist for determining the correct configuration of Spark. I will go through these and let you know if I have further questions.

Re: spark-defaults.conf optimal configuration
Hi Chris, Thank you for posting the question. Tuning spark configurations is a tricky task since there are a lot factors to consider. The configurations that you listed cover the most them. To understand the situation that can guide you in making a decision about tuning: 1) What kind of spark applications are you intending to run? 2) What cluster manager have you decided to go with? 3) How frequent are these applications going to run? (For the sake of scheduling) 4) Is this used by multiple users? 5) What else do you have in the cluster that will interact with Spark? (For the sake of resolving dependencies) Personally, I would suggest to have these questions prior to jumping on the idea of tuning. A cluster manager like YARN would help understand the settings for cores and memory since the applications have to be considered for scheduling. Hope that helps to start off in the right direction. - Neelesh S.

Re: spark-defaults.conf
So no takers regarding why spark-defaults.conf is not being picked up. Here is another one: If Zookeeper is configured in Spark why do we need to start a slave like this: spark-1.3.0-bin-hadoop2.4/sbin/start-slave.sh 1 spark://somemaster:7077 i.e. why do we need to specify the master url explicitly Shouldn't Spark just consult with ZK and us the active master? Or is ZK only used during failure? On Mon, Apr 27, 2015 at 1:53 PM, James King jakwebin...@gmail.com wrote: Thanks.
