I'd recommend looking at the S3a phase I patches and pick up those which essentially mean it's not suitable for production in 2.6 https://issues.apache.org/jira/browse/HADOOP-11571 -blocksize == 0, HTTP1.1 request abort vs close in particular. There's another thing to look at: security. What security patches will need to go into 2.6.x which can actually be done? > > Finally, I think it would be awesome to continue the release end-of-life > discussion.
