I downloaded 0.7, updated and packaged using sbt.

I was able to run zooker, but when I tried running the kafka server I got:

Error: Exception thrown by the agent : java.net.MalformedURLException:
Local host name unknown: java.net.UnknownHostException: myhostname:
myhostname

(where myhostname was my host name :)  )

Do I need to tweak the config property files or something?   I didn't touch
anything, just wanted to get it going.

I'm also want to run the performance tests, I downloaded the source from:

git://git.apache.org/kafka.git

In the perf/ folder, I don't see the run-simulatr.sh file.

I found this on github, but it seems the sbt goals perf isn't working:

./sbt project perf package-all

https://github.com/kafka-dev/kafka/tree/master/perf (I'm guessing it is
old/absolete)

I'm on ubuntu, and when I type:

>hostname

Whatever I got as an output, I put that in my server.properties file (the
hostname= option), I still get the same error when trying to start the
server.

Could you put the stack trace of the exception? Normally, you don't need to
define hostname in broker. You only need to do that if somehow the local ip
is not accessible to the clients (e.g., EC2)

Thanks,

Hi Jun,

I'm on a dedicated box, not ec2.
BTW, I am running everything (zookeeper and kafka) on the same server.
Just to recap, I'm doing everthing default as per the quickstart.
Zookeeper started just fine.
When trying to run kafka server with config/server.properties I got:

Error: Exception thrown by the agent : java.net.MalformedURLException:
Local host name unknown: java.net.UnknownHostException: myhostname:
myhostname

Why does it repeat the hostname in the exception?

That's all the exception I got, is there a way to get a more detailed
exception, is that what you are referring to?

If this helps:

>cat /etc/hosts

127.0.0.1 localhost
127.0.1.1 ubuntu

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
xx.xx.xx.xx myhostname.myhostname.com debauto

where xx.xx.xx.xx is my servers public ip, and myhostname is my domain name.

Not sure about this exception. Seems not directly related to Kafka. Did a
google search and found the following. Does that help?
