anders created YARN-2142: ---------------------------- Summary: Add one service to check the nodes' TRUST status Key: YARN-2142 URL: https://issues.apache.org/jira/browse/YARN-2142 Project: Hadoop YARN Issue Type: New Feature Components: nodemanager, resourcemanager, scheduler Affects Versions: 2.2.0 Environment: OS:Ubuntu 13.04; JAVA:OpenJDK 7u51-2.4.4-0 Reporter: anders Priority: Minor Fix For: 2.2.0
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 healthcheckservice. -- This message was sent by Atlassian JIRA (v6.2#6252)
