anders updated YARN-2142:
-------------------------
Description:
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***
