<p>The <code>reset-cluster</code> tool can be used to completely wipe out Apache Druid cluster state stored on Metadata and Deep storage. This is
intended to be used in dev/test environments where you typically want to reset the cluster before running
the test suite.
<code>reset-cluster</code> automatically figures out necessary information from Druid cluster configuration. So the java classpath
used in the command must have all the necessary druid configuration files.</p>
<p>It can be run in one of the following ways.</p>
