<p style="margin:1.2em 0px!important">At <a href="http://youtu.be/vC3lJcPq1FY?t=7m20s" target="_blank">this point in the StarCluster demo video</a>, the presenter runs the following command to list all the clusters being managed by StarCluster:</p>

</code></pre><p style="margin:1.2em 0px!important">How does StarCluster track all the clusters it’s managing? Is it through the use of EC2 instance tags? A pointer to the relevant code would also be helpful.</p>
<p style="margin:1.2em 0px!important">I’m looking to implement a feature similar to <code style="font-size:0.85em;font-family:Consolas,Inconsolata,Courier,monospace;margin:0px 0.15em;padding:0px 0.3em;white-space:pre-wrap;border:1px solid rgb(234,234,234);border-radius:3px;display:inline;background-color:rgb(248,248,248)">listclusters</code> but for <a href="http://spark.apache.org/docs/1.2.1/ec2-scripts.html" target="_blank">spark-ec2</a>. Tagging seems like the way to go to do that, but <a href="https://issues.apache.org/jira/browse/SPARK-3332" target="_blank">we had some issues with it</a> when we used it with spark-ec2.</p>
<p style="margin:1.2em 0px!important">So I’m curious to know how StarCluster did things.</p>
