Exception in client-jaas.conf :org.apache.kafka.common.KafkaException: java.lang.SecurityException: java.io.IOException: Configuration Error: Line 3: expected [=], found [username]

when I run with command in Read.md like this: java -Djava.security.auth.login.config=./server-client-jaas.conf \ -cp KafkaOffsetMonitor-assembly-0.4.6-SNAPSHOT.jar \ com.quantifind.kafka.offsetapp.OffsetGetterWeb \ --offsetStorage kafka \ --kafkaBrokers xxxx:9092 \ --kafkaSecurityProtocol SASL_PLAINTEXT \ --zk xxxx:2181 \ --port 8081 \ --refresh 10.seconds \ --retain 2.days \ --dbName offsetapp_kafka

and with my ./server-client-jaas.conf like this: KafkaClient { org.apache.kafka.common.security.plain.PlainLoginModule required     username="qingteng"     password="qeuo3GaZyXeUPy8X"; };

i got error like this: ERROR OffsetGetter$:103 - Error creating ZkUtils.

it seems that client-jaas.conf's configuration is not right. But most says this is what it should be in this conf file. So i'm wondering maybe it's my kafka version' problem. My kafka server version is : 2.3.1
