Dropping support for JDK6 in Apache Hadoop
[Apologies for the wide distribution.]
Dear HBase/Hive/Pig/Oozie communities,
We, over at Hadoop are considering dropping support for JDK6 this year.
As you maybe aware we just released hadoop-2.5.0 and are now considering making the next release i.e. hadoop-2.6.0 the *last* release of Apache Hadoop which supports JDK6. This means, from hadoop-2.7.0 onwards we will not support JDK6 anymore and we *may* start relying on JDK7-specific apis.
Now, the above releases a proposal and we do not want to pull the trigger without talking to projects downstream - hence the request for you feedback.
Please feel free to forward this to other communities you might deem to be at risk from this too.
thanks,
Arun

I dont think you can generate 1.6 target classes with 1.7 source version. If we move to 1.7, we will have to publish 1.7 artifacts.

I discussed this with Srikanth and for us the only dependency is Oozie I
think. Once Oozie moved to 1.7, we should jump and use the new features
that make a lot of boilerplate code go away.

Yes, in terms of forward compatibility, my company has been certifying the

time. No problems there, in our experience.
For stopping supporting JDK6 in the near future, and enabling JDK7 feature

Yes, in terms of forward compatibility, my company has been certifying the
current Hadoop-related stack on JDK7 (both Oracle and OpenJDK) for some

I think most of the large vendors have tested JDK7, and are comfortable
with the results. JDK8 is still very new, and is not well standardized on
in the field currently.

The trouble with that as nobody who provides commercial big-data stacks is
going to to commit to java 8+ only in 2014, or the things downstream.
Switching to Java 7 now not only gives us a start to that by getting off
all pretence of Java 6 support, it frees up those QE teams from having to
look at Java 7.
While the Java 8 language changes are the really compelling ones, mandating
it right now would only postpone any switch to Java > 6.
Otherwise, I'm +1 for any switch to Java 7, and in the slider project we're
ready for it as soon as the switch can happen.

Re: Dropping support for JDK6 in Apache Hadoop

While it sounds like a topic for a different discussion (or list@), do you
think it would be too crazy to skip JDK7 completely and just go to JDK8
directly? I think downstream components like HBase, Spark and so on would be a
huge driving factor to make the same change in Hadoop and other parts of the
ecosystem.
Thoughts?

Re: Dropping support for JDK6 in Apache Hadoop
Posted by Konstantin Boudnik <co...@apache.org>.
While it sounds like a topic for a different discussion (or list@), do you
think it would be too crazy to skip JDK7 completely and just go to JDK8
directly? I think downstream components like HBase, Spark and so on would be a
huge driving factor to make the same change in Hadoop and other parts of the
ecosystem.
Thoughts?

I think we are good on HBase side, at least on the 1.x+ branches. We
are dropping support for 1.6 from HBase-1.0 onwards.

FWIW: in Bigtop we've made the switch to JDK7 for the Bigtop
0.8.0 release across the board. No major issues so far.
Thanks,
