[jira] [Updated] (SPARK-10295) Dynamic reservation in Mesos does not release when RDDs are cached

     [ https://issues.apache.org/jira/browse/SPARK-10295?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hans van den Bogert updated SPARK-10295:
----------------------------------------
    Description: 
When running spark in coarse grained mode with shuffle service and dynamic allocation, the driver does not release executors if a dataset is cached.
The console output OTOH shows:
> 15/08/26 17:29:58 WARN SparkContext: Dynamic allocation currently does not support cached RDDs. Cached data for RDD 9 will be lost when executors are removed.
However after the default of 1m, executors are not released. When I perform the same initial setup, loading data, etc, but without caching, the executors are released.

Is this intended behaviour?
If this is intended behaviour, the console warning is misleading.
