SCALA和弹性搜索:向类路径添加符号(Databricks)

Question

:)

我收到了一个错误，我不知道该如何修正..。我真的找不到这个SchemaRDD类型的优秀文档，以及如何使用它。

build.sbt包含：

scalaVersion := "2.11.12"

libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.4.0"
libraryDependencies += "org.scalaj" %% "scalaj-http" % "2.4.1"
libraryDependencies += "io.spray" %%  "spray-json" % "1.3.5"
libraryDependencies += "com.amazonaws" % "aws-java-sdk-core" % "1.11.534"
libraryDependencies += "com.amazonaws" % "aws-encryption-sdk-java" % "1.3.6"
libraryDependencies += "com.amazonaws" % "aws-java-sdk" % "1.11.550"
libraryDependencies += "com.typesafe" % "config" % "1.3.4"
libraryDependencies += "org.elasticsearch" %% "elasticsearch-spark-1.2" % "2.4.4"

错误：

Symbol 'type org.apache.spark.sql.SchemaRDD' is missing from the classpath.
[error] This symbol is required by 'value org.elasticsearch.spark.sql.package.rdd'.
[error] Make sure that type SchemaRDD is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.
[error] A full rebuild may help if 'package.class' was compiled against an incompatible version of org.apache.spark.sql.

非常感谢大家的支持！)

依赖elasticsearch-spark-1.2是用于Spark1.x的，需要使用elasticsearch-spark-20代替。最新版本是为Spark2.3而建的

libraryDependencies += "org.elasticsearch" %% "elasticsearch-spark-20" % "7.1.1"
