      Description

      Steps to reproduce.

      Start spark shell by providing a K8s master. Then turn the debug log on,

      scala> sc.setLogLevel("DEBUG")
      
      sc.setLogLevel("DEBUG")
      
      scala> 2018-09-26 09:33:54 DEBUG ExecutorPodsLifecycleManager:58 - Removed executors with ids  from Spark that were either found to be deleted or non-existent in the cluster.
      2018-09-26 09:33:55 DEBUG ExecutorPodsLifecycleManager:58 - Removed executors with ids  from Spark that were either found to be deleted or non-existent in the cluster.

      2018-09-26 09:34:05 DEBUG ExecutorPodsLifecycleManager:58 - Removed executors with ids  from Spark that were either found to be deleted or non-existent in the cluster.
      2018-09-26 09:34:06 DEBUG ExecutorPodsLifecycleManager:58 - Removed executors with ids  from ...
      

      The fix is easy, first check if there are any removed executors, before producing the log message.
