> Before 2.0, we will pass a HTableDescriptor and the CPs can modify the schema of a table, but now we will pass a TableDescriptor, which is immutable. I think it is correct to pass an immutable instance here, but we should have a return value for this method to allow CPs to return a new TableDescriptor.
