[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.

We can move to 1.7 but also generate 1.6 artifacts?

I think the restriction is already removed in oozie trunk. 4.1 release
should have the fix

[Seetharam Venkatesh <ve...@innerzeal.com>]

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.
