連接kafka集群，有一個kafka機器連接失敗

到該kafka機器上查詢kafka進程，發現沒有，

再查看zookeeper狀態，提示 Error contacting service. It is probably not running.

[root@localhost bin]# ./zkServer.sh status
JMX enabled by default
Using config: /home/stevens/zookeeper/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

查看了其他兩個zookeeper設備，狀態都是如此，之后停掉zookeeper重啟，其他兩臺zookeeper 狀態正常，最開始發現的zookeeper 還是狀態不正確

[root@localhost bin]# ./zkServer.sh stop
JMX enabled by default
Using config: /home/stevens/zookeeper/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
[root@localhost bin]# ./zkServer.sh start
JMX enabled by default
Using config: /home/stevens/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost bin]# ./zkServer.sh status
JMX enabled by default
Using config: /home/stevens/zookeeper/bin/../conf/zoo.cfg
Mode: leader

方法： 刪除zookeeper 本地log的Version-2文件夾

[root@localhost logs]# cd /home/stevens/data/zookeeper/logs
[root@localhost logs]# rm -rf version-2/
[root@localhost logs]# cd ..
[root@localhost zookeeper]# cd data
[root@localhost data]# rm -rf version-2/

之后再重啟zookeeper 狀態就正常了
