> Because of critical computing environment ,we must test every node's TRUST 
> status in the cluster (We can get the TRUST status by the API of OAT 
> sever),So I add this feature into hadoop's schedule .
> By the TRUST check service ,node can get the TRUST status of itself,
> then through the heartbeat ,send the TRUST status to resource manager for 
> scheduling.
> In the scheduling step,if the node's TRUST status is 'false', it will be 
> abandoned until it's TRUST status turn to 'true'.
> ***The logic of this feature is similar to node's health checkservice.
> ***Only in branch-2.2.0 , not in trunk***
