Imran Rashid commented on SPARK-23308:
--------------------------------------
I think the problem is that its really tricky to know which exceptions look
like a corrupted file and which don't, especially as {{readFunction()}} is
somewhat generic there. Yeah, SocketTimeException is perhaps worth a retry ...
Did you run into this? Do you have a full stack trace of when you got a
SocketTimeoutException and the rest of the content was ignored?
> ignoreCorruptFiles should not ignore retryable IOException

> Key: SPARK-23308
> URL: https://issues.apache.org/jira/browse/SPARK-23308
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.1
> Reporter: Márcio Furlani Carmona
> Priority: Minor
>
> When `spark.sql.files.ignoreCorruptFiles` is set it totally ignores any kind
> of RuntimeException or IOException, but some possible IOExceptions may happen
> even if the file is not corrupted.
> One example is the SocketTimeoutException which can be retried to possibly
> fetch the data without meaning the data is corrupted.
