上下文:我正在开发一个Spark流工作,使用这个库将数据写入InfluxDB .这是环境.

• 斯卡拉2.11.8
• Spark 2.1.0(Dockerized独立集群)

相关依赖:

"org.apache.spark" %% "spark-core" % "2.1.0" % "provided",
"org.apache.spark" %% "spark-streaming" % "2.1.0" % "provided",
"org.apache.spark" %% "spark-streaming-kafka-0-8" % "2.1.0",
"com.paulgoldbaum" %% "scala-influxdb-client" % "0.5.2" // which uses "org.asynchttpclient" % "async-http-client" % "2.0.24"

一切都在我的本地计算机上编译并运行良好,但是当我将程序集jar提交给Spark集群时,我在驱动程序中收到此错误:
