Hi,
The submitting applications guide in http://spark.apache.org/docs/latest/submitting-applications.html says: Alternatively, if your application is submitted from a machine far from the worker machines (e.g. locally on your laptop), it is common to usecluster mode to minimize network latency between the drivers and the executors. Note that cluster mode is currently not supported for standalone clusters, Mesos clusters, or python applications. But there is a followed example, is this an error? and is "cluster" mode supported for standalone clusters? # Run on a Spark Standalone cluster in cluster deploy mode with supervise ./bin/spark-submit \ --class org.apache.spark.examples.SparkPi \ --master spark://207.184.161.138:7077 \ --deploy-mode cluster --supervise --executor-memory 20G \ --total-executor-cores 100 \ /path/to/examples.jar \ 1000
