-
-<div class="documentation-content"><p>The Storm UI daemon provides a REST API that allows you to interact with a Storm cluster, which includes retrieving
-metrics data and configuration information as well as management operations such as starting or stopping topologies.</p>
-
-<h1 id="data-format">Data format</h1>
-
-<p>The REST API returns JSON responses and supports JSONP.
-Clients can pass a callback query parameter to wrap JSON in the callback function.
-<strong>REST API allows CORS by default.</strong></p>
-
-<h1 id="using-the-ui-rest-api">Using the UI REST API</h1>
-
-<p><em>Note: It is recommended to ignore undocumented elements in the JSON response because future versions of Storm may not</em>
-<em>support those elements anymore.</em></p>
-
-<h2 id="rest-api-base-url">REST API Base URL</h2>
-
-<p>The REST API is part of the UI daemon of Storm (started by <code>storm ui</code>) and thus runs on the same host and port as the
-Storm UI (the UI daemon is often run on the same host as the Nimbus daemon). The port is configured by <code>ui.port</code>,
-which is set to <code>8080</code> by default (see <a href="conf/defaults.yaml">defaults.yaml</a>).</p>
-
-<p>The API base URL would thus be:</p>
-<div class="highlight"><pre><code class="language-" data-lang="">http://<ui-host>:<ui-port>/api/v1/...
-</code></pre></div>
-<p>You can use a tool such as <code>curl</code> to talk to the REST API:</p>
-<div class="highlight"><pre><code class="language-" data-lang=""># Request the cluster configuration.
-# Note: We assume ui.port is configured to the default value of 8080.
-$ curl http://<ui-host>:8080/api/v1/cluster/configuration
-</code></pre></div>
-<h2 id="impersonating-a-user-in-secure-environment">Impersonating a user in secure environment</h2>
-
-<p>In a secure environment an authenticated user can impersonate another user. To impersonate a user the caller must pass
-<code>doAsUser</code> param or header with value set to the user that the request needs to be performed as. Please see SECURITY.MD
-to learn more about how to setup impersonation ACLs and authorization. The rest API uses the same configs and acls that
-are used by nimbus.</p>
-
-<p>Examples:</p>
-<div class="highlight"><pre><code class="language-no-highlight" data-lang="no-highlight"> 1. http://ui-daemon-host-name:8080/api/v1/topology/wordcount-1-1425844354\?doAsUser=testUSer1
- 2. curl 'http://localhost:8080/api/v1/topology/wordcount-1-1425844354/activate' -X POST -H 'doAsUser:testUSer1'
-</code></pre></div>
-<h2 id="get-operations">GET Operations</h2>
-
-<h3 id="api-v1-cluster-configuration-get">/api/v1/cluster/configuration (GET)</h3>
-
-<p>Returns the cluster configuration.</p>
