I'm not sure if this is a good idea. Yes, you save one shuffle, but you also need to collect data to the driver side and distribute it later to run table insertion, which I don't think is cheaper than a shuffle, and is probably more fragile (causes driver OOM) -- This is an automated message from the Apache Git Service.
