--------------------------------
Summary: Handle shuffle fetch failures in decommissions
Key: SPARK-44635
URL: https://issues.apache.org/jira/browse/SPARK-44635
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 4.0.0
Reporter: Bo Zhang
Spark's decommission feature supports migration of shuffle data. However
shuffle data fetcher will only look at the location (`BlockManagerId`) when it
is initialized. This can lead to shuffle fetch failures when the shuffle read
tasks are long.
