title: Can not override Talend job context parameters when launching from the command-line
body: <p>I am currently trying to run a Talend job from the command line. Since my production environment parameters are different from what I have on my local workstation, I have to provide <strong>context parameters</strong> when launching the job on the target server:</p>
  
  <pre><code>kaffein@coffeeshop:~$ ./job_run.sh --context_param port=1234 --context_param server=myserver
  </code></pre>
  
  <p>When I exported the job though, Talend Open Studio (for data integration) generated <strong>Default.properties</strong> files for all my subjob folders. These files contain my <strong>local default context parameters</strong>.</p>
  
  <p>Launching my job with the production parameters (like shown above) then fails because it seems that the "local" parameters cannot be overriden by the command-line parameters (--context_param arguments) provided.</p>
  
  <p>Can someone help me on this issue please ?</p>
