Hi , I have a use case,
where i need to merge three data set and build one where ever data is available. And my dataset is a complex object. Customer - name - string - accounts - List<Account> Account - type - String - Adressess - List<Address> Address -name - String ---- --- And it goes on. These file are in parquet , All 3 input datasets are having some details , which need to merge. And build one dataset , which has all the information ( i know the files which need to merge ) I want to know , how should I proceed on this ?? - my approach is to build case class of actual output and parse the three dataset. ( but this is failing because the input response have not all the fields). So basically , what should be the approach to deal this kind of problem ? 2nd , how can i convert parquet dataframe to dataset, considering the pauquet struct does not have all the fields. but case class has all the field ( i am getting error no struct type found) Thanks Manjay Kumar 8320 120 839
