---------------------------------------
Summary: 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: Bug
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.
