在 Intellij 中运行 Spark 时出错：“object apache is not a member of package org”

Question

I am running a Spark program on Intellij and getting the below error : "object apache is not a member of package org".

I have used these import statement in the code :

import org.apache.spark.SparkContext  
import org.apache.spark.SparkContext._  
import org.apache.spark.SparkConf

The above import statement is not running on sbt prompt too. The corresponding lib appears to be missing but I am not sure how to copy the same and at which path.

Answer 1

Make sure you have entries like this in SBT:

scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
  "org.apache.spark" %% "spark-core" % "2.1.0", 
  "org.apache.spark" %% "spark-sql" % "2.1.0" 
)

Then make sure IntelliJ knows about these libraries by either enabling "auto-import" or doing it manually by clicking the refresh-looking button on the SBT panel.

Answer 2

It is about 5 years since the previous answer, but I had the same issue and the answer mentioned here did not work. So, hopefully this answer works for those who find themselves in the same position I was in.

I was able to run my scala program from sbt shell, but it was not working in Intellij. This is what I did to fix the issue:

1. Imported the build.sbt file as a project.

File -> Open -> select build.sbt -> choose the "project" option.

2. Install the sbt plugin and reload Intellij.

File -> settings -> Plugins -> search and install sbt.

3. Run sbt.

Click "View" -> Tool Windows -> sbt. Click on the refresh button in the SBT window.

Project should load successfully. Rebuild the project.

4. Select your file and click "Run". It should ideally work.
