kafka 更新後啟動報錯

錯誤：

啟動zookeeper報錯如下：

ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)

java.io.IOException: No snapshot found, but there are log entries. Something is broken!

啟動kafka報錯如下：

ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

kafka.common.InconsistentClusterIdException: The Cluster ID vpQcYvrnSf64z6hqo5ZjLg doesn't match stored clusterId Some(g0MqhijcQaqy5E9MeJtIrA) in m

eta.properties. The broker is trying to join the wrong cluster. Configured zookeeper.connect may be wrong.

解決：

清理上一個版本留下來的緩存資訊

cd /tmp/zookeeper/     #zookeeper.properties中dataDir對應的值
rm -rf *
           

cd /tmp/kafka-logs    #server.properties中log.dirs 對應的值
rm -rf *
           

然後重新啟動即可。
