Tom White commented on HADOOP-7269:
-----------------------------------

This looks good. Can you run Jets3tNativeS3FileSystemContractTest to check that 
it works against real S3? You can set credentials in src/test/core-site.xml.

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

> 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.
