Subject [jira] [Created] (HADOOP-7269) S3 Native should allow customizable file meta-data (headers)

S3 Native should allow customizable file meta-data (headers)

                 Key: HADOOP-7269
                 URL: https://issues.apache.org/jira/browse/HADOOP-7269
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs/s3
            Reporter: Nicholas Telford
            Priority: Minor

The S3 Native FileSystem currently writes all files with a set of default headers:

 * Content-Type: binary/octet-stream
 * Content-Length: <computed from object size>
 * Content-MD5: <computed from object data>

This is a good start, however many applications would benefit from the ability to customize
(for example) the Content-Type and Expires headers for the file. Ideally the implementation
should be abstract enough to customize all of the available S3 headers and provide a facility
for other FileSystems to specify optional file metadata.
