Regarding org.apache.spark.sql.AnalysisException error when creating a jar file using Scala
问题 I have following simple Scala class , which i will later modify to fit some machine learning models. I need to create a jar file out of this as i am going to run these models in amazon-emr . I am a beginner in this process. So i first tested whether i can successfully import the following csv file and write to another file by creating a jar file using the Scala class mention below. The csv file looks like this and its include a Date column as one of the variables. +-------------------+-------
