@timmylicheng, #280 should be done first so that metadata tables can handle schema evolution.
Updating a schema works fine, I'm referencing it so that we have a guide for building partition spec evolution. I think the two APIs should be similar.
Updating a partition spec is currently a manual operation because there is no API for making the change. You can build a replacement spec and add it to a table, though. Unfortunately, you might need to do that by editing JSON, depending on what methods we expose to update partition specs in `TableMetadata`.
