> We have a Dataset with a schema such as the following: 
>  
>  
> {code:java}
> struct<foo: struct<bar: string>>
> {code}
>  
>  
> if we do the following, one would expect to override the type of bar, but instead a new column gets added
>  
>  
> {code:java}
> ds.withColumn("foo.bar", ...){code}
>  
> This produces the following schema
>  
> {code:java}
> struct<foo: struct<bar: string>, foo.bar: ...>{code}
>
