> It is currently possible to create a table (and possibly RecordBatch) with duplicated column names, which leads to later issues when trying to analyse the data - see the below example.
> An appropriate error should be raised instead of letting duplicate names to be used
>  
> {code:java}
> > Table$create(iris, iris) %>% filter(Species == "versicolor")
> Error in schm$GetFieldByName(name)$ToString() : attempt to apply non-function
> {code}
