[jira] [Created] (HADOOP-17774) bytesRead FS statistic showing twice the correct value in S3A

Mehakmeet Singh created HADOOP-17774:
----------------------------------------

             Summary: bytesRead FS statistic showing twice the correct value in S3A
                 Key: HADOOP-17774
                 URL: https://issues.apache.org/jira/browse/HADOOP-17774
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/s3
            Reporter: Mehakmeet Singh
            Assignee: Mehakmeet Singh


S3A "bytes read" statistic is being incremented twice. Firstly while reading in S3AInputStream and then in merge() of S3AInstrumentation when S3AInputStream is closed.

This makes "bytes read" statistic equal to sum of stream_read_bytes and stream_read_total_bytes.
