PK哥，我之前用的scala版本是2.12，现在我安装kudu1.4将scala版本降到了2.11.8，然后引入pom文件之后，执行的时候报这个错误
Exception in thread “main” java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps;
错误提示行是
val spark: SparkSession = SparkSession.builder().master(“local[2]”).appName(“logETLApp”).getOrCreate()

这是我的pom文件

4.0.0
like
