Yoon" To: "dev@hama.apache.org" Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable > run Hama with Hadoop 2.7.x, is that correct ? Yes, right. As J=C3=BAlio Pires mentioned before, hadoop 2.7.0 works with JDK 7+ only. Since important new feature of this release is supporting YARN and Mesos, I think we have to support latest hadoop. > I am fine with that as Java 6 has long gone EOL, but let's make a conscio= us decision on that (maybe worth a vote). Agree with you. I'll open the vote first. Thanks Tommaso!
