Review Comment:
   @danny0405 , thanks for discussion. Then current changes in this MR could be 
merged, 51f1bb1996c8c15d094dfe56f20004d8da0440a2 throws exception for COW when 
we try to do multiple bulk inserts. And I will try to find solution for native 
Spark row writer case, in this case we have completely different call stack.
