[jira] [Created] (SPARK-4280) In dynamic allocation, add option to
never kill executors with cached blocks
Sandy Ryza created SPARK-4280:
---------------------------------
Summary: In dynamic allocation, add option to never kill executors with cached blocks
Key: SPARK-4280
URL: https://issues.apache.org/jira/browse/SPARK-4280
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 1.2.0
Reporter: Sandy Ryza
Even with the external shuffle service, this is useful in situations like Hive on Spark where a query might require caching some data. We want to be able to give back executors after the job ends, but not during the job if it would delete intermediate results.
