zookeeper Error contacting service 解决

连接kafka集群，有一个kafka机器连接失败

到该kafka机器上查询kafka进程，发现没有，

再查看zookeeper状态，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.

查看了其他两个zookeeper设备，状态都是如此，之后停掉zookeeper重启，其他两台zookeeper 状态正常，最开始发现的zookeeper 还是状态不正确

[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： 删除zookeeper 本地log的Version-2文件夹

[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/

之后再重启zookeeper 状态就正常了
