   This patch looks good to me and test passed.
   - Some job info will be lost before this patch

   The master branch did not find this bug. But this patch still can be 
cherry-pick to the master branch to prevent this bug.

> Existing JobOutput's extend info will be lost when it is updated. The update 
> will replace the previous info(map) with new one, but the new one doesn't 
> contain all old informations.
> It can cause job execute info incorrect, like duration in web ui：
