    kafka.common.ConsumerRebalanceFailedException: group_dd-1446432618163-2746a209 can't rebalance after 10 retries

    解决办法:
    1.配置zk问题(kafka的consumer配置)
    zookeeper.session.timeout.ms=5000
    zookeeper.connection.timeout.ms=10000
    rebalance.backoff.ms=2000
    rebalance.max.retries=10



    官方解释:
    consumer rebalancing fails (you will see ConsumerRebalanceFailedException): This is due to conflicts when two consumers are trying to own the same topic partition. The log will show you what caused the conflict (search for "conflict in ").
    If your consumer subscribes to many topics and your ZK server is busy, this could be caused by consumers not having enough time to see a consistent view of all consumers in the same group. If this is the case, try Increasing rebalance.max.retries and rebalance.backoff.ms.
    Another reason could be that one of the consumers is hard killed. Other consumers during rebalancing won't realize that consumer is gone after zookeeper.session.timeout.ms time. In the case, make sure that rebalance.max.retries * rebalance.backoff.ms > zookeeper.session.timeout.ms.
