Subject Error while producing messages
Date Sat, 09 Aug 2014 00:02:39 GMT
Hi,



I am trying to do capacity sizing estimate for our kafka cluster. I started with 5 broker
cluster and 3 node zk. Used a simple java based producer to send messages to 5 topics that
are created in the cluster. I used 2 client machines with 100 worker threads each sending
messages continuously. I didn't see any exceptions or issues when all 5 brokers are up. When
I take down 3 brokers out of 5, and 4 topics out of 5. I am seeing below in broker logs.

On the client machine(producer) I am seeing below error. Again only one topic and 2 broker
nodes are running.

Not all messages are erroring out. Only a few messages are failing. Any idea what could be
going on?



Thanks,
