-------------------------------------------
Summary: S3 Native filesystem does not retry all connection
failures
Key: HADOOP-12353
URL: https://issues.apache.org/jira/browse/HADOOP-12353
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.7.1
Reporter: Mariusz Strzelecki
Assignee: Mariusz Strzelecki
Priority: Minor
Current implementation of NativeS3FileSystem.java uses RetryProxy that retries
exceptions that may occur on network communication with S3 API, but these
exceptions must be exact instances of IOException:
https://github.com/apache/hadoop/blob/master/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3native/NativeS3FileSystem.java#L349
Our tests show that HttpClient throws IOException subclasses which are not
handled by Proxy.
