are no errors in the state change log or in the controller log.
One thing i found is this one happens only at starting time. I mean the
first time, when i start kafka and try to insert the messages i see this
error.

What i did:
started 3 kafka processes in my system.The config is default config with
just the ports and log dir's changed.There are 3 zookeeper servers
running.
If i start the console producer next time it will work fine.
To reproduce what did was, stopped all the kafka and zookeeper process,
deleted the log dirs of the kafka and the zookeeper and restated the
processes.
Thanks

Could you do a list topic and show the output? Also, any error in the
controller and state-change log?

Can some one please let me know why this is happening.
I checked my vhost files and localhost, my hostname are correct.
