That usually happens when you have different types for a column in some
parquet files.
In this case, I think you have a column of `Long` type that got a file with
`Integer` type, I had to deal with similar problem once.
You would have to cast it yourself to Long.

I am getting following error after performing joins between 2 dataframe. It
happens on call to .show() method. I assume it's an issue with incompatible
type but it's been really hard to identify which column of which dataframe
have that incompatibility.
Any pointers?
