启用 DSE 统一身份验证后"DSE 火花"失败

Question

i将DSE更新为5.1.2，并启用了DSE统一身份验证。

当我运行" dse -u xxx -p xxx spark"时，我会得到一个外壳，但是如果我使用" spark.sql"提交查询，我会收到错误：

scala> val result = spark.sql("SELECT id FROM xxx.yyy")
java.lang.RuntimeException: com.datastax.bdp.fs.client.InternalServerException: Server returned HTTP error response  500 (Internal Server Error)
Caused by: com.datastax.bdp.fs.client.InternalServerException: Server returned HTTP error response  500 (Internal Server Error)
  at com.datastax.bdp.fs.client.DseFsClient$stateMachine$macro$1$1.apply(DseFsClient.scala:132)

in/var/log/cassandra/system.log我看到：

WARN  [Native-Transport-Requests-2] 2017-08-31 12:05:29,057  DseAuthenticator.java:659 - Plain text authentication without client / server encryption is strongly discouraged

任何想法如何解决此问题。顺便说一句，DSE Spark-Submit可以工作...

通过在dse.yaml中启用dsef。
