Yup, we'll need to update the documentation.

 Yes, @Charith you have few options..

 1) Build a single jar/bundle by wrapping necessary dependencies and use.

Hi All,

Thank you very much for the thoughts & suggestions.

After went through the discussion, I have followed steps suggested
by Grainier and was able to add kafka receiver without any issue. Btw,
apart from proving the jar, I think we should update documentations because
provided steps are not work for some kafka/scala versions. WDYT?

Thanks & Regards,

 AFAIU there's no straightforward way to workaround this issue as it
 requires to two different versions of the same .jar other than upgrading
 the Spark scla-library dependency.

Re: [Dev] [DAS] java.lang.NoSuchMethodError when trying to add Kafka Event Receiver

2016-06-05 Thread Grainier Perera 
As +sajith mentioned, DAS already have scala 2.10.x packed for spark. And
Kafka packs two binary builds for multiple versions of Scala (Scala
2.10/Scala 2.11) [1]. So, you should use kafka_2.10-0.9.0.1.tgz and copy
it's jar files as dependencies, and when adding dependencies to
/components/lib/, *do not add scala-library-2.10.5.jar,* since it's already
available with DAS 3.0.1

[1] http://kafka.apache.org/downloads.html

+1. I think building a proper jar with the correct dependencies would be
good since that way we can use the latest version of Kafka. WDYT?

Also, @Charitha, can you try putting the scala-library to dropins instead
of lib. From looking at the jar, it already has an OSGi manifest file, so
no need to OSGify it again. Did we try starting the server without putting
the scala-library-2.11.7.jar at all? Anyway, since this is an OSGi binding
issue, there might be some non-standard bundle combinations that can get it
to work. But that wouldn't be a clean solution I think.

Thanks,
Lasantha

Re: [Dev] [DAS] java.lang.NoSuchMethodError when trying to add Kafka Event Receiver

2016-06-05 Thread Sajith Ravindra 
It seems Spark has a dependency on scala-library_2.10.4 and this jar is
already included in DAS pack, therefore copying scala-library-2.11.7.jar as
per the documentation will lead to a conflict. I tested deleting
./repository/components/plugins/org.scala-lang.scala-library_2.10.4.v20140209-180020-VFINAL-b66a39653b.jar
in DAS pack and it fixes the above error. But it give a NoClassDefFound
error in startup.

AFAIU there's no straightforward way to workaround this issue as it
requires to two different versions of the same .jar other than upgrading
the Spark scla-library dependency.

P.S : @Charith if this is for the sake of testing you can use CEP as it has
not scala-libarary dependency.
