> Project: Apache Arrow
> Issue Type: Improvement
> Reporter: Nic Crane
> Assignee: Nic Crane
> Priority: Major

> 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
>

> > Table$create(iris, iris) %>% filter(Species == "versicolor")
> Error in schm$GetFieldByName(name)$ToString() : attempt to apply non-function
> {code}
