------------------------------------
Summary: Disk-persisted RDD blocks served by shuffle service, and
ignored for Dynamic Allocation
Key: SPARK-27677
URL: https://issues.apache.org/jira/browse/SPARK-27677
Project: Spark
Issue Type: New Feature
Components: Block Manager, Spark Core
Affects Versions: 2.4.3
Reporter: Imran Rashid
Disk-cached RDD blocks are currently unavailable after an executor is removed.
However, when there is an external shuffle service, the data remains available
on disk and could be served by the shuffle service. This would allow dynamic
allocation to reclaim executors with only disk-cached blocks more rapidly, but
still keep the cached data available.
