Rebalancing issue while reading messages in Kafka

问题:

I am trying to read messages on Kafka topic, but I am unable to read it. The process gets killed after sometime, without reading any messages.

Here is the rebalancing error which I get:

[2014-03-21 10:10:53,215] ERROR Error processing message, stopping consumer:  (kafka.consumer.ConsoleConsumer$) kafka.common.ConsumerRebalanceFailedException: topic-1395414642817-47bb4df2 can't rebalance after 4 retries     at kafka.consumer.ZookeeperConsumerConnector$ZKRebalancerListener.syncedRebalance(ZookeeperConsumerConnector.scala:428)     at kafka.consumer.ZookeeperConsumerConnector.kafka$consumer$ZookeeperConsumerConnector$$reinitializeConsumer(ZookeeperConsumerConnector.scala:718)     at kafka.consumer.ZookeeperConsumerConnector$WildcardStreamsHandler.(ZookeeperConsumerConnector.scala:752)     at kafka.consumer.ZookeeperConsumerConnector.createMessageStreamsByFilter(ZookeeperConsumerConnector.scala:142)     at kafka.consumer.ConsoleConsumer$.main(ConsoleConsumer.scala:196)     at kafka.consumer.ConsoleConsumer.main(ConsoleConsumer.scala) Consumed 0 messages

I tried to run ConsumerOffsetChecker, and this is the error which I get. I have no clue whatsoever, how to resolve this. Anybody, any idea?
