+1 on librdkafka interop

Minor nitpick:

 KAFKA-1781 (state required gradle version in README)  is included in the Release notes but is not actually fixed

[Jun Rao]

I think we were just confirming whether that issue was fixed in 0.8.2 not. Given that this issue only happens in unclean shutdown, I don't think it's a blocker for 0.8.2. Also, the patch is not trivial and it's better to test it out a bit longer in trunk.

Thanks,

Jun

In meetup we said that KAFKA-1650 and follow up patches is included in
0.8.2, but it seems not on the list.

This is a reminder that the vote will close tomorrow night. Please test RC3 out and vote before the deadline.

Thanks,

Hi, Alex,

Thanks for testing RC3. 

Broker.connectionString() is actually not part of the public api for the producer. Is there a particular reason that you need to use this api?

Thanks,

Jun

Hello,

I have read Broker.scala source code, and I found the answer:
 - With Kafka 0.8.1.1 we used Broker.getConnectionString() in our Java code.
 - With Kafka 0.8.2.0, this method has been replaced by a 0-arity method
without the "get" prefix, so we have to change our Java code to call
Broker.connectionString()

So despite binary compatibility is broken, we have a by-pass.
I hope this will help other people relying on this API...

and I'm going to continue tests with 0.8.2 rc3..

The following are the results of the votes.

+1 binding = 3 votes
+1 non-binding = 1 votes
-1 = 0 votes
0 = 0 votes

The vote passes.

I will release artifacts to maven central, update the dist svn and download site. Will send out an announce after that.

Thanks everyone that contributed to the work in 0.8.2.0!
