I am running into the following error when running ALS Exception in thread "main" java.lang.NoSuchMethodError: scala.reflect.api.JavaUniverse.runtimeMirror(Ljava/lang/ClassLoader;)Lscala/reflect/api/JavaMirrors$JavaMirror; at org.apache.spark.ml.recommendation.ALS.fit(ALS.scala:452) at yelp.TestUser.main(TestUser.java:101)
here line 101 in the above error is the following in code. ALSModel model = als.fit(training); Does anyone has a suggestion what is going on here and where I might be going wrong ? Please suggest -VG
