[jira] [Created] (HADOOP-16900) Very large files can be truncated when written through S3AFileSystem

Andrew Olson created HADOOP-16900:
-------------------------------------

             Summary: Very large files can be truncated when written through S3AFileSystem
                 Key: HADOOP-16900
                 URL: https://issues.apache.org/jira/browse/HADOOP-16900
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/s3
            Reporter: Andrew Olson


If a written file size exceeds 10,000 * {{fs.s3a.multipart.size}}, a corrupt truncation of the S3 object will occur as the maximum number of parts in a multipart upload is 10,000 as specific by the S3 API and there is an apparent bug where this failure is not fatal.
