Comment 2 for bug 1285070

@ Raghavendra D Prabhu (raghavendra-prabhu)

  1.It would cause a lot of duplicate key error if a batch of replace statements has executed on the source node and then insert rows on the other nodes. The lead a accident in my application.

   2.I just confirm replace command so far ， suppose that commands which lead a different auto-increment counter between master and slave could have the problem.

thanks
