java - 使用phoenix在Hbase上保存数据框

Question

就像标题所说，我想用phoenix保存我的DataFrame。
我在intellij IDEA上运行的scala中有一个 Spark 代码。
这很简单:

import org.apache.spark.sql.SparkSession
import org.apache.phoenix.spark._

object MainTest extends App {
  val sparkSession = SparkSession.builder()
    .config("spark.sql.warehouse.dir", "file:///c:/tmp/spark-warehouse")
    .master("local[*]")
    .appName("spark-to-hbase")
    .getOrCreate()

  val sc = sparkSession.sparkContext
  val sqlC = sparkSession.sqlContext
  import sqlC.implicits._

  val myRdd = sc.parallelize(List(("a",1), ("b", 2)))
  myRdd.collect.foreach(println)
  val myDf = myRdd.toDF("column1", "column2")
  myDf.show()
  myDf.saveToPhoenix("MY_TABLE", zkUrl = Some("localhost:16000"))
}

我也有一个HBase数据库在端口16000上的同一台PC上运行。
问题是线

myDf.saveToPhoenix("MY_TABLE", zkUrl = Some("localhost:16000"))

抛出此异常:

据我了解，java似乎找不到某些类。
我能做什么 ？

我的SBT:

name := "spark-to-hbase"

version := "1.0"

scalaVersion := "2.11.8"

libraryDependencies ++= Seq(
  "org.apache.hadoop" % "hadoop-mapreduce-client-core" % "2.3.0",
  "org.apache.phoenix" % "phoenix-core" % "4.11.0-HBase-1.3",
  "org.apache.spark" % "spark-core_2.11" % "2.1.1",
  "org.apache.spark" % "spark-sql_2.11" % "2.1.1",
  "org.apache.phoenix" % "phoenix-spark" % "4.11.0-HBase-1.3"
)

方法saveToPhoenix采用RDD。对于数据框，请使用save(有关更多详细信息，请参见此doc):

myDf.save("org.apache.phoenix.spark", SaveMode.Overwrite,
  Map("MY_TABLE" -> "OUTPUT_TABLE", "zkUrl" -> "localhost:16000"))
