             Summary: make mesosExecutorCores configurable in mesos "fine-grained" mode
                 Key: SPARK-6350
                 URL: https://issues.apache.org/jira/browse/SPARK-6350
             Project: Spark
          Issue Type: Improvement
            Reporter: Jongyoul Lee
            Priority: Minor


When spark runs in mesos fine-grained mode, mesos slave launches executor with # of cpus and
memories. By the way, # of executor's cores is always CPU_PER_TASKS as same as spark.task.cpus.
If I set that values as 5 for running intensive task, mesos executor always consume 5 cores
without any running task. This waste resources. We should set executor core as a configuration
variable.
