@zhengcanbin ,@StephanEwen ,@shijinkui. After push this issue, we must
illustrate in flink configuration. If we want to use kerberos authentication
with ZK server, we must set zookeeper.sasl.disable:false and set the
security.kerberos.login.contexts:zookeeper. But before, we only set
security.kerberos.login.contexts:zookeeper. Thanks!
