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

             Summary: Failures of undeploy of a partially failed deployment
                 Key: WFLY-4203
                 URL: https://issues.jboss.org/browse/WFLY-4203
             Project: WildFly
          Issue Type: Bug
          Components: CLI, Domain Management
    Affects Versions: 8.2.0.Final
            Reporter: Arcadiy Ivanov
            Assignee: Alexey Loubyansky

[domain at localhost:9990 /] undeploy 2e3b75f2-88ff-4eb9-a8b1-9107c452309e.ear --all-relevant-server-groups
Undeploy failed: JBAS010839: Operation failed or was rolled back on all servers.
{noformat}

There are several issues at play here:
# Insufficient information is displayed along with JBAS010839
# No actual failure logged either in DC or in individual host's logs
# Failure to find a deployment unit on a particular host should not result in a failure of a domain-wide undeploy in DeploymentUndeployHandler

I'll start in a reverse order of causation:

in DeploymentUndeployHandler.execute
{noformat}
    public void execute(OperationContext context, ModelNode operation) throws OperationFailedException {
        ModelNode model = context.readResourceForUpdate(PathAddress.EMPTY_ADDRESS).getModel();
...
{noformat}

OperationContextImpl.readResourceForUpdate calls OperationContextImpl.requireChild:

{noformat}
    private static Resource requireChild(final Resource resource, final PathElement childPath, final PathAddress fullAddress) {
        if (resource.hasChild(childPath)) {
            return resource.requireChild(childPath);
        } else {
            PathAddress missing = PathAddress.EMPTY_ADDRESS;
            for (PathElement search : fullAddress) {
                missing = missing.append(search);
                if (search.equals(childPath)) {
                    break;
                }
            }
            throw ControllerMessages.MESSAGES.managementResourceNotFound(missing);
        }
    }
{noformat}

The exception generated by {{throw ControllerMessages.MESSAGES.managementResourceNotFound(missing);}}: 
# does not propagate from the host to DC and to CLI
# is not logged with any level (not even TRACE) either on host or DC
# should be handled within DeploymentUndeployHandler not to fail the undeploy operation in case of a partially failed deployment (e.g. EAR with unsatisfied CDI dependencies).
