hadoop ondemand feature?

Hi,
  I know that hadoop is more suitable for patch processing.  But is there a 
ondemand feature in hadoop?  I want hadoop to process a specific user's 
information when the user demands it in the web interface.  I am thinking maybe 
setting a priority to this specific user's information, so hadoop will process 
it immediately when it is doing its own patch processing, is it possible?  If 
not, any idea of a workaround?
Thanks.

btw, when I said "user's information", it is just my system's data.  It can be 
any kinds of data, like word count.  e.g., I want to process word count of a 
specific word immediately. 

Thanks.
