wenweijian commented on SPARK-34788:
------------------------------------
I can reproduce it.
If the performance impact of the proposal (SyncFailedException) is little, I
think it is worth fixing
> Spark throws FileNotFoundException instead of IOException when disk is full

> Key: SPARK-34788
> URL: https://issues.apache.org/jira/browse/SPARK-34788
> Project: Spark
> Issue Type: Improvement
> Components: Shuffle, Spark Core
> Affects Versions: 3.2.0
> Reporter: wuyi
> Priority: Major
>
> When the disk is full, Spark throws FileNotFoundException instead of
> IOException with the hint. It's quite a confusing error to users：
> {code:java}
> 9/03/26 09:03:45 ERROR ShuffleBlockFetcherIterator: Failed to create input

> （The cause only says the file is not found, but we believe it's highly
> possible due to the disk full issue after investigation.）
> And there's probably a way to detect the disk full: when we get
> `FileNotFoundException`, we try
> [http://weblog.janek.org/Archive/2004/12/20/ExceptionWhenWritingToAFu.html]
> to see if SyncFailedException throws. If SyncFailedException throws, then we
> throw IOException with the disk full hint.
