------------------------------------------
Summary: Fetching the remote disk stored RDD blocks via the
external shuffle service is not working
Key: SPARK-51639
URL: https://issues.apache.org/jira/browse/SPARK-51639
Project: Spark
Issue Type: Bug
Components: Block Manager
Affects Versions: 4.0.0, 4.1.0, 3.5.6
Reporter: Attila Zsolt Piros
Assignee: Attila Zsolt Piros
After https://issues.apache.org/jira/browse/SPARK-43221, remote fetching of
disk-stored RDD blocks is not working.
The getLocationsAndStatus method does not use the external shuffle service when
the blocks are not host-local. The fallback to extend the search to all
executors only includes the active executors, so after downscaling, blocks
stored on a killed executor will not be found there which leads to recompute.
