Hi How can I rename nested columns in dataframe through scala API? Like following schema
> |-- site: struct (nullable = false) > > | |-- site_id: string (nullable = true) > > | |-- site_name: string (nullable = true) > > | |-- site_domain: string (nullable = true) > > | |-- site_cat: array (nullable = true) > > | | |-- element: string (containsNull = false) > > | |-- publisher: struct (nullable = false) > > | | |-- site_pub_id: string (nullable = true) > > | | |-- site_pub_name: string (nullable = true) > I want to change it to > |-- site: struct (nullable = false) > > | |-- id: string (nullable = true) > > | |-- name: string (nullable = true) > > | |-- domain: string (nullable = true) > > | |-- cat: array (nullable = true) > > | | |-- element: string (containsNull = false) > > | |-- publisher: struct (nullable = false) > > | | |-- id: string (nullable = true) > > | | |-- name: string (nullable = true) > > Regards Prashant
