当我从kakfa_2.12-2.3.0中的程序包运行zookeeper时，出现以下错误

$ export KAFKA_OPTS="-Djava.security.auth.login.config=/kafka/kafka_2.12-2.3.0/config/zookeeper_jaas.conf"
    $ ./bin/zookeeper-server-start.sh  config/zookeeper.properties

而zookeeper_jaas.conf是

KafkaServer {
   org.apache.kafka.common.security.plain.PlainLoginModule required
   username="admin"
   password="admin-secret"
   user_admin="admin-secret";
};

而zookeeper.properties文件是

server=localhost:9092
#server=localhost:2888:3888
sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required username="ibm" password="ibm-secret";

security.protocol=SASL_SSL
sasl.mechanism=PLAIN
ssl.truststore.location=**strong text**/kafka/apache-zookeeper-3.5.5-bin/zookeeperkeys/client.truststore.jks
ssl.truststore.password=test1234

 authProvider.1=org.apache.zookeeper.server.auth.SASLAuthenticationProvider 
 jaasLoginRenew=3600000 
 requireClientAuthScheme=sasl 

谁能建议可能是什么原因

我试图在selenium IDE中使用javascript设置下拉值,但无法确定要使用哪个selenium命令.
