I notice a exception when start bellow

org.apache.zookeeper.ClientCnxn - Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)

This is not an exception, but tells you which mode is turned on.

The report is quite vague that seems having no valuable information.

cc @BewareMyPower is it a typical Python client issue? If not, I tend to close this one as information incompleted.

[BewareMyPower]

No. Since it uses Python 2.7, it could be a very old client version. Python client 3.x only supports Python 3.7 or higher.
