java.io.IOException: No snapshot found, but there are log entries

一 问题描述

启动zookeeper报错：

[2021-05-10 11:12:35,798] INFO zookeeper.snapshotSizeFactor = 0.33 (org.apache.zookeeper.server.ZKDatabase)

[2021-05-10 11:12:35,815] ERROR Unexpected exception, exiting abnormally (org.apache.zookeeper.server.ZooKeeperServerMain)

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

 ……

zookeeper配置文件定义的dataDir路径是/tmp，我看根目录磁盘空间100%了，推测磁盘空间不足导致的zookeeper启动失败。

我删除了之前的几个log文件，还是报错。

二 解决办法

#迁移zookeeper的数据目录

这里从/tmp下迁移到/opt/kafka/zookeeper下

cd /opt/kafka

mkdir zookeeper

将zookeeper配置文件路径改为了/opt/kafka/zookeeper：

cd /opt/kafka/config

vi zookeeper.properties

dataDir=/opt/kafka/zookeeper

 

#启动zookeper

bin/zookeeper-server-start.sh config/zookeeper.properties &

 

#启动kafka也报错：

[2021-05-10 11:22:43,263] ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

kafka.common.InconsistentClusterIdException: The Cluster ID VLPFfY-WQkWmK7X9_C1aHQ doesn't match stored clusterId Some(0TVA9OzOTzCGMTqY50sBKA) in meta.properties. The broker is trying to join the wrong cluster. Configured zookeeper.connect may be wrong.

       at kafka.Kafka.main(Kafka.scala)

解决办法：

cd /tmp/kafka-logs  #kafka的Log.dirs路径

cp meta.properties meta.properties_bak

修改 meta.properties中的cluster.id值，示例：

我这里将0TVA9OzOTzCGMTqY50sBKA改成了VLPFfY-WQkWmK7X9_C1aHQ
