------------------------------------

             Summary: DUCC RM should detect duplicate nodes and stop schedulng to them.
                 Key: UIMA-3705
                 URL: https://issues.apache.org/jira/browse/UIMA-3705
             Project: UIMA
          Issue Type: Improvement
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger
            Priority: Minor


If the Resource Manager detects duplicate node agents with different UUIDs attempting to join
the DUCC cluster it should deallocate all work on the affected nodes and stop scheduling to
that node until some intervention is performed to stop the duplicate(s) and communicate to
RM that the node/agents have been cleaned up.
