<p>
This class runs the <a href="../../gobblin/cluster/GobblinHelixJobScheduler.html" title="class in gobblin.cluster"><code>GobblinHelixJobScheduler</code></a> for scheduling and running Gobblin jobs.
This class serves as the Helix controller and it uses a <code>HelixManager</code> to work with Helix.

<p>
This class will initiates a graceful shutdown of the cluster in the following conditions:
<ul>
<li>A shutdown request is received via a Helix message of subtype
<a href="../../gobblin/cluster/HelixMessageSubTypes.html#APPLICATION_MASTER_SHUTDOWN"><code>HelixMessageSubTypes.APPLICATION_MASTER_SHUTDOWN</code></a>. Upon receiving such a message,
it will call <a href="../../gobblin/cluster/GobblinClusterManager.html#stop--"><code>stop()</code></a> to initiate a graceful shutdown of the cluster</li>
<li>The shutdown hook gets called. The shutdown hook will call <a href="../../gobblin/cluster/GobblinClusterManager.html#stop--"><code>stop()</code></a>, which will
start a graceful shutdown of the cluster.</li>
