>                 URL: https://issues.apache.org/jira/browse/SPARK-9731
>             Project: Spark
>          Issue Type: Bug
>          Components: Deploy
>    Affects Versions: 1.5.0
>            Reporter: Carson Wang

> The issue only happens if `spark.executor.cores` is not set and executor memory is set
to a high value. 
> For example, if we have a worker with 4G and 10 cores and we set `spark.executor.memory`
to 3G, then only 1 core is assigned to the executor. The correct number should be 10 cores.
