             Summary: DUCC's Agent Should Stop Publishing Metrics via Admin 
Channel Request
                 Key: UIMA-2877
                 URL: https://issues.apache.org/jira/browse/UIMA-2877
             Project: UIMA
          Issue Type: New Feature
          Components: DUCC
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik


To support taking nodes off line in an orderly manner, the agent should stop 
publishing its metrics when requested. The RM detects that the node is down and 
will not schedule any new work. The existing work will be preempted and moved 
elsewhere. The request will arrive via DUCC's admin channel. The agent will 
check if it is a target node for the message and immediately stop the Camel 
route which drives the collection and publishing of metrics.
