FAQ
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.
