Exception in thread “main“ java.lang.NoSuchMethodError: scala.Product.$init$(Lscala/Product；)V

I am getting the following error when running spark code in idea

error:

Exception in thread "main" java.lang.NoSuchMethodError: scala.Product.$init$(Lscala/Product;)V
    at org.apache.spark.SparkConf$DeprecatedConfig.<init>(SparkConf.scala:809)

    at cn.itcast.spark.wordcount.main(wordcount.scala

reason¶

after some check I found:

• The corresponding version of spark is 2.12
• scala version is 2.11

solution¶

The problem is solved after changing the scala version to 2.12
