2014-04-24 Thread Bert Corderman 
I had this error before and corrected by increasing nofile limit

add to file an entry for the user running the broker.

/etc/security/limits.conf

kafka - nofile 98304

you can use the kafka-list-topic.sh to find out if leader for particual
topic is available.-1 in leader column might indicate trouble.

Re: Kafka Performance Tuning

2014-04-24 Thread Yashika Gupta 
I had cleaned up the topics using the following commands:

Rm -rf /tmp/kafka-logs/*
And verified using the topics list command before executing the script.

Am I missing anything else.

I am running a single broker and the leader column has 0 as the value.

RE: Kafka Performance Tuning

2014-04-24 Thread Yashika Gupta 
Jun,

I am using Kafka 2.8.0- 0.8.0 version.
There are no logs for the past month in the controller and state-change log.

Though I can see dome gc logs in the kafka-home-dir/logs folder.
zookeeper-gc.log
kafkaServer-gc.log

Re: Kafka Performance Tuning

2014-04-24 Thread Timothy Chen 
Hi Yashika,

No logs in broker log is not normal, can you verify if you turned off
logging in your log4j properties file?

If it is please enable it and try again, and see what is in the logs.

My 8 consumers are running in parallel with different consumer group ids and 
trying to read from LOGLINE10.
2 of them are able to read the LOGLINE10 topic but the 6 others are failing 
with the above exception.

Hi Yashika,

No logs in broker log is not normal, can you verify if you turned off
logging in your log4j properties file?

If it is please enable it and try again, and see what is in the logs.

Re: Kafka Performance Tuning

2014-04-25 Thread Jun Rao 
The socket timeout may be due to this: MaxWait: 6 ms. So, you need to
set socket.timeout.ms in consumer config (defaults to 30 secs) to be larger
than 60 secs since your fetch request could take up to 60 secs.

Thanks,

Jun
