Setting Executor memory

Hello, I was looking for guidelines on what value to set executor memory to (via spark.executor.memory for example). This seems to be important to avoid OOM during tasks, especially in no swap environments (like AWS EMR clusters). This setting is really about the executor JVM heap. Hence, in

Setting executor memory when using spark-shell

Hi All, Please help me set Executor JVM memory size. I am using Spark shell and it appears that the executors are started with a predefined JVM heap of 512m as soon as Spark shell starts. How can I change this setting? I tried setting SPARK_EXECUTOR_MEMORY before launching Spark shell: export

Re: Setting executor memory when using spark-shell

Hi Oleg, I set the size of my executors on a standalone cluster when using the shell like this: ./bin/spark-shell --master $MASTER --total-executor-cores $CORES_ACROSS_CLUSTER --driver-java-options -Dspark.executor.memory=$MEMORY_PER_EXECUTOR It doesn't seem particularly clean, but it works.

Re: Setting executor memory when using spark-shell

Thank you, Andrew, I am using Spark 0.9.1 and tried your approach like this: bin/spark-shell --driver-java-options -Dspark.executor.memory=$MEMORY_PER_EXECUTOR I get bad option: '--driver-java-options' There must be something different in my setup. Any ideas? Thank you again, Oleg On 5

Re: Setting executor memory when using spark-shell

Oh my apologies that was for 1.0 For Spark 0.9 I did it like this: MASTER=spark://mymaster:7077 SPARK_MEM=8g ./bin/spark-shell -c $CORES_ACROSS_CLUSTER The downside of this though is that SPARK_MEM also sets the driver's JVM to be 8g, rather than just the executors. I think this is the reason
