[jira] [Updated] (SPARK-42737) Shuffle files lost with graceful decommission fallback storage enabled
[ https://issues.apache.org/jira/browse/SPARK-42737?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yeachan Park updated SPARK-42737:
---------------------------------
Description:
During testing of graceful decommissioning, the driver logs indicate that shuffle files were lost - `DAGScheduler: Shuffle files lost for executor`:

This seems incorrect as there were no shuffle files to migrate to begin with. We enabled:
- spark.decommission.enabled
- spark.storage.decommission.rddBlocks.enabled
- spark.storage.decommission.shuffleBlocks.enabled
- spark.storage.decommission.enabled
and set spark.storage.decommission.fallbackStorage.path to a path in our bucket.
The same also happened when there were actual shuffle files that were stored in the bucket.
