> s3a failures can surface as RTEs, not IOEs
> ------------------------------------------
>
> Key: HADOOP-13130
> URL: https://issues.apache.org/jira/browse/HADOOP-13130
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.7.2
> Reporter: Steve Loughran
>
> S3A failures happening in the AWS library surface as
> {{AmazonClientException}} derivatives, rather than IOEs. As the amazon
> exceptions are runtime exceptions, any code which catches IOEs for error
> handling breaks.
> The fix will be to catch and wrap. The hard thing will be to wrap it with
> meaningful exceptions rather than a generic IOE. Furthermore, if anyone has
> been catching AWS exceptions, they are going to be disappointed. That means
> that fixing this situation could be considered "incompatible" —but only for
> code which contains assumptions about the underlying FS and the exceptions
> they raise.
