[jira] [Created] (SPARK-9731) Standalone scheduling incorrect cores if spark.executor.cores is not set

             Summary: Standalone scheduling incorrect cores if spark.executor.cores is not set
                 Key: SPARK-9731
                 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.
