------------------------------------------
Maybe we should just make it Unstable?
> IOStatistics API in branch-3.3 break compatibility
> --------------------------------------------------

> Key: HADOOP-17673
> URL: https://issues.apache.org/jira/browse/HADOOP-17673
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Wei-Chiu Chuang
> Priority: Critical
>
> The S3 delegation token feature (3.3.0) added API
> {code:java}
> AmazonS3 createS3Client(URI name,
> String bucket,
> AWSCredentialsProvider credentialSet,
> String userAgentSuffix) throws IOException;
> {code}
> However, the IOStatistics API (HADOOP-17271, HADOOP-13551. in 3.3.1) changed
> it to
> {code:java}
> AmazonS3 createS3Client(URI name,
> String bucket,
> AWSCredentialsProvider credentialSet,
> String userAgentSuffix) throws IOException; {code}
> The API is declared evolving, so we're not supposed to break compat between
> maintenance releases.
