<h1 id="resetcluster-tool">ResetCluster tool</h1>
<p>ResetCluster tool can be used to completely wipe out Apache Druid (incubating) 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.
ResetCluster 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>
