Chandni Singh updated SPARK-36255:
----------------------------------
Summary: FileNotFound exceptions from the shuffle push can cause the
executor to terminate (was: FileNotFound exceptions in the Shuffle-push-thread
can cause the executor to fail)
> FileNotFound exceptions from the shuffle push can cause the executor to
> terminate

> Key: SPARK-36255
> URL: https://issues.apache.org/jira/browse/SPARK-36255
> Project: Spark
> Issue Type: Sub-task
> Components: Shuffle
> Affects Versions: 3.1.0
> Reporter: Chandni Singh
> Priority: Major
>
> When the shuffle files are cleaned up by the executors once a job in a Spark
> application completes, the push of the shuffle data by the executor can throw
> FileNotFound exception. When this exception is thrown from the
> {{shuffle-block-push-thread}}, it causes the executor to fail. This is
> because of the default uncaught exception handler for Spark daemon threads
> which terminates the executor when there are uncaught exceptions for the
> daemon threads.
