[jira] [Commented] (ARROW-7412) [C++][Dataset] Ensure that dataset code is robust to schemas with duplicate field names

    [ https://issues.apache.org/jira/browse/ARROW-7412?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17009057#comment-17009057 ] 

Ben Kietzman commented on ARROW-7412:
-------------------------------------

For now, we should probably just error if a field is referenced whose name is not unique.

> Fields in a schema don't have to have unique names, so we should make sure we're not assuming that.
