Idea debugs locally, and spark reports an error when creating hivecontext

Spark version: 1.6.1

Scala version: 2.10

problem scenario:

when idea debugged the local program, an error was reported when creating the hivecontext. This problem was not found in the morning. In the afternoon, a small Deamon was written in the project. This problem occurred. Here is my code:

import org.apache.spark.sql.hive.HiveContext

object test{
  def main(args: Array[String]): Unit = {
    SparkConfig.init("local[2]", this.getClass.getName)
    val sc = SparkConfig.getSparkContext()
    val hqlContext = new HiveContext(sc)


error reporting:


  After worrying all morning, I thought my dependency package was not downloaded at first, but there was this package in the build.sbt file in my SBT. I tracked the source code, looked for Du Niang, and so on. Finally, I found the problem. Finally, I located the problem because the type setting of the spark hive dependency package was wrong:

By the way, how do I find the build.sbt file in idea

The culprit is this word, which needs to be changed to “compile”, as shown in the following figure:

Then, click the prompt in the lower right corner, import:

Wait until the update is completed, and then compile here. Success

Big pit, record it here to prevent encountering it again in the future
