> Key: SPARK-21115
> URL: https://issues.apache.org/jira/browse/SPARK-21115
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.1.1
> Reporter: eaton
> Priority: Minor
>
> If we start an app with the param --total-executor-cores=4 and spark.executor.cores=3, the cores left is always 1, so it will try to allocate executors in the function org.apache.spark.deploy.master.startExecutorsOnWorkers in every schedule.
> Another question is, is it will be better to allocate another executor with 1 core for the cores left.
