Scala Datastax 1.2 java驱动程序

我正在运行DSE 3.2.1 并使用datastax java驱动程序cassandra-driver-core-1.0.5-dse.jar

可以确认DSE已启动且侦听器已配置：

# lsof -p 27418 |grep -i listen |sed 's/^/    /'
java    27418 alan  202u  IPv4          120289525      0t0       TCP *:48749 (LISTEN)
java    27418 alan  203u  IPv4          120289526      0t0       TCP *:7199 (LISTEN)
java    27418 alan  204u  IPv4          120289527      0t0       TCP *:49952 (LISTEN)
java    27418 alan  209u  IPv4          120291873      0t0       TCP *:8983 (LISTEN)
java    27418 alan  224u  IPv4          120291754      0t0       TCP karma:afs3-fileserver (LISTEN)
java    27418 alan  227u  IPv4          120289911      0t0       TCP *:8009 (LISTEN)
java    27418 alan  259u  IPv4          120291894      0t0       TCP karma:9042 (LISTEN)
java    27418 alan  260u  IPv4          120291895      0t0       TCP karma:9160 (LISTEN)
@karma:conf  grep -i native *yaml |grep -v ^#
start_native_transport: true
native_transport_port: 9042

但无法使用此驱动程序连接。Scala代码：

  import com.datastax.driver.core.
  ... 
  def open() {
  logger.info("DatastaxEnterprise cluster host: {} port: {}", host, port)
  cluster = Cluster.builder.addContactPoint(host).withPort(port).build

获取此例外：

14:55:47.562 [run-main] DEBUG com.datastax.driver.core.Cluster - Shutting down

有什么想法吗？此驱动程序是否使用端口9160或9042？ 使用此处的参考代码示例：

TIA，JM.

我认为您需要确保类路径中有Guava 14.0.1。真正的问题是SBT引入的是Guava 13.0.1，而不是14。我试着强迫它使用14版，但没有成功。我怎样才能解决它？我如何判断哪种包装取决于番石榴13。将可视化依赖关系树。请参阅有关如何排除错误依赖项的问题
