Hi joeyang,

Which Kafka version is it? (1.4 or 2.0)
Does the parcel tab show kafka service as activated?
While adding the service it just asks for broker instances and mirrormaker is optional.
At what stage do you get the error?

Hi, Siddesh2104

Thanks for prompt response,

1. csd(kafka-1.2.0.jar) from http://archive.cloudera.com/csds/kafka/
parcel(KAFKA-2.0.1-1.2.0.1.p0.5-trusty.parcel) from: http://archive.cloudera.com/kafka/parcels/latest/

3. yes, parcel has been activated as attached

4. the red color warning message prevent us from clicking "continue", we got stuck on the page as attached, nothing happened after we pressed "continue"

Any more advice would be appreciated.

Thanks

Joe

While adding the Kafka service, have you added mirrormaker role as well?
If yes, can you try without adding it?

joeyang — Mon, 09 May 2016 09:56:00 GMT

yes, without selecting mirror , we can press continue, then we hit the following errors as attached,

any further advice would be appreciated

Hi, please perform the following actions:

1) Fill in "Source Brokers List" --> "nameOfClouderaKafkaBrokerServer.yourdomain.com:9092". This is the Server (or Servers) where you configured the Kafka Broker (NOT the MirrorMaker).

2) Fill in "Destination Brokers List" --> "nameOfRemoteBrokerServer.otherdomain.com:9092". This is supposed to be a remote Cluster that will receive Topics sent over by your MirrorMaker. If you have one, put in that one. Otherwise just put in another Server in your network, whatever Server.

Please note that both this Server Names must be FQDN and resolvable by your DNS (or hosts file), otherwise you'll get other errors. Also the format with the trailing Port Number is mandatory!

3) Click "Continue". Service will NOT start (error). Do not navigate away from that screen

4) Open another Cloudera Manager in another browser pane. You should now see "Kafka" in the list of Services (red, but it should be there). Click on the Kafka Service and then "Configure".

5) Search for the "java heap space" Configuration Property. The standard Java Heap Space you'll find already set up should be 50 MBytes. Put in at least 256 MBytes. The original value is simply not enough.

6) Now search for the "whitelist" Configuration Property. In the field, put in "(?!x)x" (without the quotation marks). That's a regular expression that does not match anything. Given that apparently a Whitelist is mandatory for the Mirrormaker Service to start, and I'm assuming you don't want to replicate any topics remotely right now, just put in something that won't replicate anything e.g. that regular expression.

7) Save the changes and go back to the original Configuration Screen on the othe browser pane. Click "Retry", or wathever, or even exit that screen and manually restart the Kafka Service in Cloudera Manager.

That should work, at least it did for me! HTH

we followed this official link to test kafka:
http://www.cloudera.com/documentation/kafka/latest/topics/kafka_command_line.html

not sure why ther's no any error message, it got back to prompt

Re: adding a Kafka service failed

joeyang — Thu, 26 May 2016 05:53:01 GMT

it works with the following command:
kafka-topics --create --zookeeper cloudera01 --topic ggz --partitions 1 --replication-factor 1
kafka-console-producer --broker-list cloudera02:9092 --topic ggz
kafka-console-consumer --zookeeper cloudera01:2181 --topic ggz --from-beginning

Toughdev — Fri, 26 Aug 2016 05:23:45 GMT

Could you please give me what exactly to put into these fields on CDH kafka configuring.

1) Fill in "Source Brokers List" --> "nameOfClouderaKafkaBrokerServer.yourdomain.com:9092". This is the Server (or Servers) where you configured the Kafka Broker (NOT the MirrorMaker).

2) Fill in "Destination Brokers List" --> "nameOfRemoteBrokerServer.otherdomain.com:9092". This is supposed to be a remote Cluster that will receive Topics sent over by your MirrorMaker. If you have one, put in that one. Otherwise just put in another Server in your network, whatever Server.

Toughdev — Fri, 26 Aug 2016 05:24:36 GMT

I have given Destination Broker List as
quickstart.cloudera:9092

Source Broker List as

Hi Joe,

nameOfClouderaKafkaBrokerServer.yourdomain.com:9092

What are the actual values we can give for nameOfClouderaKafkaBrokerServer? yourdomain?

Is port number 9092 same always?

Please ignore .. i see this questions is answered in Page 2 🙂 Very good topic.

Thanks,

Chandra
