"Setup local environment" step results in error #5

gaydenko · 2016-04-22T10:16:53Z

Hi!

After pulling kafka I have copied/pasted from README.md the string ./gralew install - boom!.. d char is missed. Ok, after fixing the typo I get:

Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

Have I missed something?
Gradle 2.12 is installed under Arch Linux.

The text was updated successfully, but these errors were encountered:

michal-harish · 2016-04-22T11:15:13Z

Hi, you need to run gradle in the Kafka source dir before running ./gradlew install - I have updated the README (and fixed the typo), thanks! Try and if you encounter some other problem continue in this thread, otherwise close, thanks.

gaydenko · 2016-04-22T11:32:50Z

Thanks! - now gradlew finishes with success. But zookeeper start results in Error: Could not find or load main class org.apache.zookeeper.server.quorum.QuorumPeerMain. Have I missed some presumed pre-requirements?

I guess some steps is missed as far as official binary distribution contains libs directory, while pulled one doesn't.

michal-harish · 2016-04-22T12:00:33Z

Looks like you're running on windows. in that case you need to use zookeeper-server-start.bat and kafka-server-start.bat respectively instead of the bash scripts. I will update the instructions for windows users..

gaydenko · 2016-04-22T12:05:11Z

What are these windows? :) No, as I have mentioned, I run Arch Linux.

michal-harish · 2016-04-22T12:22:02Z

I see (missed the linux mention). I have just tried on a new user (on mac) and it worked - could be that you may need to run ./gradlew jar install - going to try on a linux vm and will update.

gaydenko · 2016-04-22T12:31:39Z

I guess -PscalaVersion=2.11 options was needed. Now I have already created all topics. But can not build the project istself:

 $ ./gradlew build
:compileJava/some/dir/hello-kafka-streams/src/main/java/org/apache/kafka/connect/api/ConnectEmbedded.java:76: error: no suitable constructor found for DistributedHerder(DistributedConfig,Time,Worker,StatusBackingStore,String)
        herder = new DistributedHerder(config, time, worker, statusBackingStore, "");

    constructor DistributedHerder.DistributedHerder(DistributedConfig,Worker,String,StatusBackingStore,ConfigBackingStore,WorkerGroupMember,String,Time) is not applicable

michal-harish · 2016-04-22T12:36:17Z

Yes, -PscalaVersion-2.11 was missing - have added. The last error is probably because kafka trunk has changed since the demo was written (it moves fast). Looking at it

gaydenko · 2016-04-22T12:38:20Z

Probably it takes some sense to checkout concrete kafka commit to become free from constant updating the project to be in sync with kafka trunk.

michal-harish · 2016-04-22T12:46:17Z

Either that, or use 0.10.0.0 tag which has release candidates already so will be more-less stable.

gaydenko · 2016-04-22T12:59:20Z

@michal-harish ,

Yes! - all OK is now with 0.10.00 tag, thanks!

Cool, thanks for your time - others will have it easier! I will update the master build and instructions to use 0.10.0.0 instead of trunk..

phderome · 2016-06-05T18:53:46Z

I am apparently getting same build compile error as described Apr 22 on "new DistributedHerder" and my build.gradle file shows ext.kafkaVersion = '0.10.0.0'. I used git clone on https://github.com/amient/hello-kafka-streams.git. I have two compile errors, that's second one whereas first one says:
JsonPOJOSerde.java:28: error: JsonPOJOSerde is not abstract and does not override abstract method close

I am on OSX Capitan.

michal-harish · 2016-06-05T19:02:58Z

Hi. Yes, I have just tried (deleted my 0.10.0.0 jars) and it fails. There
must have been changes in the kafka 0.10 release back-ported onto the
0.10.0.0 release. I'll update the hello program tonight.

it should work on master now - confluent platform branch still needs updating for their 3.0 platform release.

phderome · 2016-06-05T22:21:47Z

yes, thanks!

phderome · 2016-06-05T22:45:50Z

I see proper behaviour at run-time but previously there were quite a few
Java exception traces about files not being there. Am I doing something
visibly wrong?

You're not doing anything wrong. I've seen those too first time I run it -
I suspect some Reflections incompatibility. I will take a look at this when
I'll be upgrading the cp branch.
