title: Nomad : Unable to Run a python script
body: <p>I am trying to submit the following job to my nomad server. The job basically uses a payload which is a python file from my localhost. </p>
  
  <pre><code>job "agent-collector-bot" {
    datacenters = ["staging"]
  
    type = "batch"
  
    periodic {
      cron             = "*/10 * * * *"
      prohibit_overlap = true
    }
  
    group "python-bot" {
      count = 1
      task "slack-bot" {
        driver = "raw_exec"
  
        config {
          command = "python"
          args = ["local/agent-collector-slackbot.py"]
        }
  
        dispatch_payload {
         file = "agent-collector-slackbot.py"
       }
  
      }
    }
  }
  </code></pre>
  
  <p>Now when i see the job status in nomad it says:</p>
  
  <p>snomad status agent-collector-bot/</p>
  
  <pre><code>ID            = agent-collector-bot/periodic-1512465000
  Name          = agent-collector-bot/periodic-1512465000
  Submit Date   = 12/05/17 14:40:00 IST
  Type          = batch
  Priority      = 50
  Datacenters   = staging
  Status        = pending
  Periodic      = false
  Parameterized = false
