Hi Muthu,
I checked in the ZK cli, I can see my created topic.Steps:-//enter the ZK shell
zookeeper-shell.sh crazybox:2181ls /brokers/topics[kafkatopic] -- this is the 
topic that I created.
Thanks,Bhargo

 Hi Muthu,
Thanks for replying.PFB my replies:-
Is your ZK running on the same system as one of broker instance ? 
Yes, ZK, broker,console-producer, console-consumer are running on the same box
 -       Is broker able to connect to ZK properly ? May be this can be checked 
via ZK CLI tools to check if the broker registrations happen properly as soon 
as you start Kafka brokerI don't think this should be a problem because my 
console producer can send the messages to the console consumers. But, to be 
double sure of it, I will verify this.
 -       Is your topic created and accessible via ‘sudo ./bin/kafka-topics.sh’ 
command remotely with –describe flag? 
Yes,I can see my topic listed when I use the command - kafka-topics.sh 
--describe kafkatopic --zookeeper crazybox:2181
 -       Was console-producer and console-consumer run from a remote machine to 
check if they really work with the remote broker config changes you have done ? 
They are run locally so there are no remote connections involved.
Thanks,Bhargo

mainly due to firewall restrictions in my setup with remote VM running broker 
and ZK. In my little experience, few things to check concretely before running 
our own clients to see if the changes of server.properties is properly done    
-       Is your ZK running on the same system as one of broker instance ? -     
  Is broker able to connect to ZK properly ? May be this can be checked via ZK 
CLI tools to check if the broker registrations happen properly as soon as you 
start Kafka broker -       Is your topic created and accessible via ‘sudo 
./bin/kafka-topics.sh’ command remotely with –describe flag?  -       Was 
console-producer and console-consumer run from a remote machine to check if 
they really work with the remote broker config changes you have done ?     This 
can help troubleshooting where the issue lies.    Regards Muthu       From:

Subject: Error while publishing messages    Hi Team!!    I am working on a POC 
for my project, where I want to replace RabbitMQ with Kafka I am using the 
0.9.0.1 version of kafka on my Ubuntu 15.10  version. I have been able to setup 
the basic setup, where from the console producer I can send messages and from 
the console consumer, I can consume them as well. But, when I try to create a 
java program to send the messages to the same topic, I get an exception 
stacktrace in my IDE console and my console consumer shows the same message 4 
times.    The exception that I get is the following:- Exception in thread 
"main" kafka.common.FailedToSendMessageException: Failed to send messages after 
3 tries.
    at 
kafka.producer.async.DefaultEventHandler.handle(DefaultEventHandler.scala:91)
    at kafka.producer.Producer.send(Producer.scala:77)
    at kafka.javaapi.producer.Producer.send(Producer.scala:33)
    at com.bhargo.main.MainClass.publishMessage(MainClass.java:47)
    at com.bhargo.main.MainClass.main(MainClass.java:58)    I am not sure what 
the issue is, I have made sure that server.properties file that is used to 
startup my broker has the correct configurations:- 
zookeeper.connect=crazybox:2181 advertised.port=9092 
advertised.host.name=crazybox host.name=crazybox port=9092    On running the 
command hostname , I get the result as "crazybox" and hostname -i, gives me 
127.0.0.1 I am attaching the code for your reference. Please have a look once.  
  Any help here is much appreciated.    Thanks, Bhargo
