liuxian created SPARK-22085:
-------------------------------

             Summary: When the applicationhas no core left,do not request more executors
 from the cluster manager in ExecutorAllocationManager
                 Key: SPARK-22085
                 URL: https://issues.apache.org/jira/browse/SPARK-22085
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.3.0
            Reporter: liuxian
            Priority: Minor


When the application has no core left,we should not request more executors  from the cluster
manager in `ExecutorAllocationManager`.
At this time, if not reach `spark.dynamicAllocation.maxExecutors`, `spark.dynamicAllocation.maxExecutors`setting
is invalid in fact, so we should give a warning log.
