Review Comment:
   @yihua I don't think we should remove this check. It is deliberately added 
to cover cases when bootstrapped table have had upserts. After the initial 
bootstrap, new upserts will have all the columns written in the hudi table. At 
that time I believe it will also have the partition column and then we should 
start treating it as a normal table.
