Zombie service registered if Service name is changed

[calvn]

I encountered an issue where a Task was registered to Consul as service under a specific name, but after changing the name the old task name was still registered, in addition to the new one.

Initially I had this JSON Service object in the job spec:

...
"Services": [
  {
    "Name": "helloworld",
    "PortLabel": "http"
  }
],
...

Running this job registered the helloworld.service.dc1.consul service. I then changed the service name to be the following:

...
"Services": [
  {
    "Name": "nomad-helloworld",
    "PortLabel": "http"
  }
],
...

This registered nomad-helloworld.service.dc1.consul, but helloworld.service.dc1.consul was also still registered.

@cleung2010 This will be fixed in 0.3

I see we keep registering the service once it's name changes infinitely but we do remove the old service. So not sure why you are seeing a zombie service, we know the problem but taking some time to handle updates to allocations in a nicer way.

It seems that when I delete a job, the services on that job do not get deregistered. Don't know if this should be a separate issue.

Edit: Wrong API call on my part on this one, please disregard.

@cleung2010 Can you post your job description for that? I can't reproduce.

[calvn]

@diptanu regarding the job deletion? That's a mistake on my part, it's working as intended.

[diptanu]

@cleung2010 Yeah I was asking about the job deletion. We know what's happening when the service name changes, a fix will land soon. Taking some time to handle updates properly.

@diptanu by zombie service I meant the state of the service registration and not the actual service (that service does get removed/replaced).
