1. we can create znodes normally

2020-07-12 09:52:22,663 [myid:localhost:2181] - INFO  [main-SendThread(localhost:2181):ClientCnxn$SendThread@1420] - Session establishment complete on server localhost/0:0:0:0:0:0:0:1:2181, session id = 0x10001a6779c0b5a, negotiated timeout = 30000WATCHER::WatchedEvent state:SyncConnected type:None path:null

[zk: localhost:2181(CONNECTED) 2]                                                                                  

2. However, "zkServer.sh status" doesn't work, after restarting the server, it works

[root@zk-test001 bin]# ./zkServer.sh status
/usr/bin/java

Using config: /data/software/apache-zookeeper-3.6.1-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Error contacting service. It is probably not running.
