[jira] [Created] (HADOOP-17673) IOStatistics API in branch-3.3 break compatibility

Wei-Chiu Chuang created HADOOP-17673:
----------------------------------------

             Summary: 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


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.
