Spark根据jdbc将数据保存到MYSQL到其他数据库

Question

我尝试根据JDBC To Other Databases enter link description here将rdd保存到外部数据库，例如mysql。

dsStream.foreachRDD( rdd => {
  val to_save_rdd = rdd.map(.../*some tranform operation*/)    
  val spark = SparkSession.builder.config(rdd.sparkContext.getConf).getOrCreate()
  import spark.implicits._
  to_save_rdd.toDF().show()
  to_save_rdd.toDF().write
  .format("jdbc")
  .option("url", "jdbc:mysql://127.0.0.1:3306")
  .option("dbtable", "db_name.table_name")
  .option("user", "root")
  .option("password", "root")
  .save()

})

然而，即使我评论 to_save_rdd.toDF（）。write.format（...）。option（...）。save ，它也会失败。错误日志如下。

java.lang.AssertionError: assertion failed: no symbol could be loaded from interface org.apache.hadoop.hbase.classification.InterfaceAudience$Public in object InterfaceAudience with name Public and classloader org.apache.spark.util.MutableURLClassLoader@5d20e46

任何建议都将受到赞赏。
