OK, I've just realised that the confluent tech.preview is based on Kafka 0.9.x - I will have to create a branch of the demo itself because the APIs are slightly different.. |

Thanks. No I didn't have kafka trunk, will try a clone and see. On Mon, Apr 11, 2016, 5:53 PM Michal Harish [email protected]

demo backported to the API version bundled with confluent platform tech.preview alpha; under 'cp' branch; tested and updated README.md setup guide |

Hi Michal, Thanks for the updates to github, instructions are clearer. There is still I will redouble my efforts on the Confluent site and see if there was any Thanks. On Tue, Apr 12, 2016 at 5:38 AM, Michal Harish [email protected]

It should be looking for connect-api-0.9.1.0-cp1.jar, if you are on the cp branch the build.gradle contains ext.kafkaVersion='0.9.1.0-cp1' and there is a dependency compile group: 'org.apache.kafka', name: 'connect-api', version: kafkaVersion |

Ok, I saw that in the java folder. What needs to change in build.gradle to Thanks. On Tue, Apr 12, 2016 at 12:39 PM, Michal Harish [email protected]

What I mean is: I have already changed it and it works correctly for me. ./gradlew clean build

BUILD FAILED I just cloned app today, after the changes you made so should be working Thanks. On Tue, Apr 12, 2016 at 1:40 PM, Michal Harish [email protected]

I have pushed the fix today so you need to pull. Can you pase here how your
|
|
Yes, here it is: apply plugin: 'application' ext.javaVersion = '1.8' sourceCompatibility = 1.8 build.dependsOn startScripts task wrapper(type: Wrapper) { repositories { dependencies { jar { Is this one good or does not match the new fix? On Tue, Apr 12, 2016 at 2:01 PM, Michal Harish [email protected]
|
|
yeah, your copy is not up-to-date. this is how the file looks in the repo: cp/build.gradle This should bring you up to date and clean: git checkout cp && git reset --hard && git pull Then again ./gradlew build |
|
Ok, will get it now. Is my file path correct for repositories? Thanks. On Tue, Apr 12, 2016 at 2:08 PM, Michal Harish [email protected]
|
|
yeah the dirs looks ok but after reset --hard you'll need to change it back to /usr/local |
|
I got new files to work with and am now running into some compilation java hduser@hduser-VirtualBox:/usr/local/hello-kafka-streams$ sudo ./gradlew ^ FAILURE: Build failed with an exception.
I am going through the java files to see if I can spot any differences, so Thanks. On Tue, Apr 12, 2016 at 2:22 PM, Michal Harish [email protected]

The log says that classes are not found > your dependencies are not loading > you haven't updated the dirs path after the resetting your copy. Anyways, closing this issue, the backport to confluent branch is done. |

Hi Michal, I know you closed this issue but had a couple questions based on the error org.apache.kafka.common.????
Thanks for the help. On Tue, Apr 12, 2016 at 4:50 PM, Michal Harish [email protected]

I followed the instructions to run this example with some limited success. Tow things are not quite clear to me;
a). the instruction to update gradle.properties in confluent is not clear - how to do it
b) my attempt to compile example resulted in a failure - missing Kafka-streams/0.10.1.0-SNAPSHOT jar file.
If I use confluent-alpha1 instead of the not yet released Kafka 0.10.1.0, how do I connect the example to the running Kafka instance?
