Re: Kafka 0.8, Scala 2.10.2, OSGi

Can you go off the 0.8 branch please? We're in the process of the 0.8.0 release so if you still have problems that were not resolved we can know what they are.

Re: Kafka 0.8, Scala 2.10.2, OSGi

Posted by "Ngu, Bob" <bo...@intel.com>.
Ok, so I guess this means there isn’t explicit support for OSGi yet, I’ll
take a look at the client rewrite when I get a chance, thanks.

Re: Kafka 0.8, Scala 2.10.2, OSGi

Posted by Joe Stein <jo...@stealth.ly>.
In regards to OSGi maybe it is something you would propose and help out
with for the client rewrite
https://cwiki.apache.org/confluence/display/KAFKA/Client+Rewrite I don't
know what is entailed for coding and long term support and what the
community benefit would be.  If you could help with any of that it would go
towards making it happening.

Re: Kafka 0.8, Scala 2.10.2, OSGi

Posted by Joe Stein <jo...@stealth.ly>.
you need a pgp keypair.

if you use sbt you could try http://www.scala-sbt.org/sbt-pgp/usage.html

or without sbt get OpenPGP installed http://linux.die.net/man/1/gpg2 and
then

gpg2 --gen-key

Thanks, I did just that, I found the kafka github repo, grabbed the 0.8
