I'm having an issue with Spark when running on Mesos in coarse grain mode no matter what options I use or how many free resources I have I only ever see two executors start.
If I run Spark in fine grain mode on Mesos I see tasks eventually ramp up to the desired number I specified. Anyone know what could be causing this? I'm starting my job using the following commands -- /usr/bin/timeout 3600 /opt/spark-1.5.1/bin/spark-submit --master "mesos://zk ://prod-zookeeper-1.aws.xxx.com:2181,prod-zookeeper-2.aws.xxx.com:2181,prod- zookeeper-3.aws.xxx.com:2181/mesos" --conf spark.ui.port=31278 --conf spark.mesos.coarse=true --conf spark.mesos.extra.cores=3 --conf spark.cores.max=5 --conf spark.mesos.constraints="rack:spark" --conf spark.sql.tungsten.enabled=true --class com.orchard.dataloader.library.originators.prosper.LoadTrade_Prosper --total- executor-cores 3 --driver-memory 1536M --executor-memory 3011M --jars /data/orchard/etc/load-tradedata-accumulo-prod /data/orchard/jars/dataloader- library-59e0441cd06544442d2a84f5842b701e81097988-assembled.jar I'm using spark-1.5.1 and Mesos 0.26 Chronos-2.4.0 is starting the spark driver. If anyone have any ideas on what/where I should be focusing on to debug this? \-- **Rodrick Brown** / Systems Engineer +1 917 445 6839 / [[email protected]](mailto:[email protected]) **Orchard Platform** 101 5th Avenue, 4th Floor, New York, NY 10003 [http://www.orchardplatform.com](http://www.orchardplatform.com/) [Orchard Blog](http://www.orchardplatform.com/blog/) | [Marketplace Lending Meetup](http://www.meetup.com/Peer-to-Peer-Lending-P2P/) -- *NOTICE TO RECIPIENTS*: This communication is confidential and intended for the use of the addressee only.
