[VOTE] Apache Hama 0.7 release (RC1)

Hey all,

I just created a first release candidate for the Apache Hama 0.7
release. This release includes new features such as Mesos, Yarn
modules and many improvements/bug fixes.

The RC1 is available at:

http://people.apache.org/~edwardyoon/dist/0.7.0-RC1/

Tags:

http://svn.apache.org/repos/asf/hama/tags/0.7.0-RC1/

Please try it, run the tests, verify checksum files, etc. and vote.

Thanks!

Yes, right. As Júlio 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.

Agree with you. I'll open the vote first.

Thanks Tommaso!

one important thing is deciding which Java version we support, as far as I
understand Edward wants to drop support for Java 6 to make it possible to
run Hama with Hadoop 2.7.x, is that correct ?

I am fine with that as Java 6 has long gone EOL, but let's make a conscious
decision on that (maybe worth a vote).

Tommaso

RE: [VOTE] Apache Hama 0.7 release (RC1)

While testing I received a NoSuchMethodError on ConcurrentHashMap$KeySetView:

java.lang.NoSuchMethodError: 
java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView

The reason is that Java 1.7 ConcurrentHashMap#keySet() returns a Set<K> while 
the 1.8 ConcurrentHashMap#keySet() returns a 
ConcurrentHashMap.KeySetView<K,V>.

I'll create new one using Java 1.7. Also, if you have any good idea for this, 
Pls let me know.
