I'm afraid it does. And I am not an owner of the cloud. It seems like a
zookeeper error, maybe? Does it need special configuration in such an
environment? I'll figure it out eventually but any help would be greatly
appreciated.

topic=LEADER_NOT_AVAILABLE

Hello,

I am trying to run a simple kafka cluster on an OpenNebula cloud. I am
using the 0.9.0. Kafka binary. Each time I try to connect to the broker
(from localhost or from a different machine), I get this error:

[kafka-producer-network-thread | producer-1] DEBUG
o.apache.kafka.clients.NetworkClient - Sending metadata request
ClientRequest(expectResponse=true, callback=null,
request=RequestSend(header={api_key=3,api_version=0,correlation_id=7,client_id=producer-1},
body={topics=[test2]}), isInitiatedByNetworkClient,
createdTimeMs=1461688260916, sendTimeMs=0) to node -1
[kafka-producer-network-thread | producer-1] WARN
o.apache.kafka.clients.NetworkClient - Error while fetching metadata with
correlation id 7 : {test2=LEADER_NOT_AVAILABLE}

my zookeeper configuration file is unchanged from default (only the data
path) and my server configuration is different in these fields:

port = 9090
host.name = 

The zookeeper and the server are both running on the same nachine. I
unlocked firewall ports 2181 and 9090 both. The producer and consumer are
configured correctly, as they worked on a different system (my home
laptop). Am I missing some important configuration?

Thanks in advance,

Re: Gradle build error

[Oliver Pačut]

I have Gradle 1.4, Groovy 1.8.6, Ant 1.9.3.

I followed the included Readme. I cd'd to the kafka directory and just
wrote "gradle".

I also tried running "./bin/kafka-server-start.sh ./config/server.properties"

And that gets me the error "Could not find or load main class Kafka.kafka"

Gradle build error

[Oliver Pačut]

Hello,

I am having trouble using Gradle to build Kafka. I get the error:


FAILURE: Build failed with an exception.

*Where:
Build file '/home/user/Desktop/kafka/build.gradle' line: 163

* What went wrong:
A problem occurred evaluating root project 'kafka'.
> Could not find property 'ScalaPlugin' on project ':clients'.


I've tried reinstalling gradle and re-downloading Kafka, to no success. I
have trouble understanding what exactly I am supposed to do; what is the
error.

Thank You in advance and Merry Christmas,

O.P.
