@kbendick I do think we should allow this, just ignoring the schema change. Currently the behavior of merge schema invalidates a write that would succeed if mergeSchema had been set to false. I think in cases like this merge schema should just not downcast and allow the write to proceed as normal. This would be really useful for users who have multiple numeric sources and want to use mergeSchema functionality. Mostly the merge schema is being used for adding new missing columns but if an existing column has a wider type (or was widened by another operation) I don't think that should break anything -- This is an automated message from the Apache Git Service.
