@cloud-fan I briefly discussed this with @gatorsmile earlier in a call. How difficult it is to add a functionality to inject null (as default values) for non existent columns ? The data frame reader's schema method is able to do this today on file sources. Is this doable ? It would help in one of our use-cases. Base Schema : StructType(f1, f2) Required schema : StructType(f1, f3) Result Schema: StructType(f1, f3) => f3 is projected as null. -- This is an automated message from the Apache Git Service.
