[jira] [Created] (SPARK-7955) Ensure executors that have cached blocks are not removed when dynamic allocation is enabled

Hari Shreedharan created SPARK-7955:

             Summary: Ensure executors that have cached blocks are not removed when dynamic allocation is enabled
                 Key: SPARK-7955
                 URL: https://issues.apache.org/jira/browse/SPARK-7955
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: Hari Shreedharan


When dynamic allocation is enabled, executor idle time is currently the only parameter considered. This can be annoying if executors get removed but have cached blocks. This can cause sever performance degradation.
