---------------------------------------
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.
