我在Kafka做poc spark流媒体工作。我可以对不安全的kafka 0.10群集使用相同的代码，但是当我切换到针对ssl/kerberos（hdp 2.5）设置运行时，我遇到了一个异常：

Caused by: javax.security.auth.login.LoginException: Could not login: the client is being asked for a password, but the Kafka client code does not currently support obtaining a password from the user. not available to garner  authentication information from the user

spark会话创建得很好，但是当执行器启动以使用来自主题的新内容时，我得到了上面的异常。
提交代码相当简单：

spark-submit \
--master yarn \
--keytab ./bilsch.keytab \
--principal bilsch@HDP.SOME.ORG \
--files kafka_client_jaas.conf,bilsch.keytab \
--packages org.apache.spark:spark-streaming-kafka-0-10_2.11:2.0.2 \
--repositories http://repo.hortonworks.com/content/repositories/releases \
--num-executors 1 \
--class producer \
--driver-java-options "-Djava.security.auth.login.config=./kafka_client_jaas.conf -Dhdp.version=2.5.3.0-37" \
--conf "spark.executor.extraJavaOptions=-Djava.security.auth.login.config=./kafka_client_jaas.conf" \
streaming_0331_2.11-1.0.jar 2>&1 | tee out

如果有帮助的话，我会跟随迈克尔·诺尔斯的《Kafka》教程
不确定哪些内容需要传递给执行器，而我还没有传递，或者可能只是jaas配置问题？
