我正在运行一个 3 节点 Spark 2.1.1 独立集群，spark.authenticate=true并且 Livy 服务器无法连接到它。这是我的一部分 livy.conf
livy.spark.authenticate = true
livy.spark.master = spark://HOSTNAME:25000
livy.spark.authenticate.secret = SECRET
在日志中我可以看到由于某种原因安全性被声明为DISABLED ，我猜这会导致这个错误跟踪......
INFO SecurityManager:54 - SecurityManager: authentication disabled; ui acls disabled; users with view permissions: Set(vva); groups with view permissions: Set(); users with modify permissions: Set(vva); groups with modify permissions: Set()
INFO StandaloneAppClient$ClientEndpoint: Connecting to master spark://x.x.xxx.xx:25000...

org.apache.spark.SparkException: Exception thrown in awaitResult:

Caused by: java.lang.RuntimeException: java.lang.IllegalStateException: Expected SaslMessage, received something else (maybe your client does not have SASL enabled?)
PS。我已经在单节点环境中进行了相同的测试，并且似乎工作正常。
谢谢。
