   >Do you have any suggestions about how to slove this probelm better?
   
   the behaviour is configurable, we can't change the default, but if you want 
this behaviour you can explicitly change the value of this conf in your prod 
cluster and get things sorted.

>  AS the default value of

> So I think it's better to make the default value as false.
