> 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.
