title: How to prevent h2o cluster shutdown without notice using R
body: <p>I am a h2o R version user and I have a question regarding the h2o local cluster. I setup the cluster by execute the command in r,</p>
  
  <p><code>h2o.init()</code></p>
  
  <p>However, the cluster will be turned off automatically when I do not use it for a few hours. For example, I run my model during the night, but when I come back to my office in the morning to check on my model. It says,</p>
  
  <p><code>Error in h2o.getConnection() : No active connection to an H2O cluster. Did you runh2o.init()?</code></p>
  
  <p>Is there a way to fix or work around it ?</p>
