+<h1 id="introduction-and-background">Introduction and Background</h1>
+<p>Slider 0.60 Uses Hadoop IPC for communications between the Slider client and the per-instance application master. This uses protobuf-formatted payloads, with the Hadoop IPC layer handling security: authorization, authentication and encryption.</p>
+<p>It provides read-only views of generated content and state through a set of web service URLs. All these services are implemented by the Jersey JAX-RS engine, operating in an embedded Jetty Web engine, with the YARN <code>AmWebFilter</code> class redirecting all requests not coming from the RM Proxy IP address to that RM Proxy via a 302 (redirect-as-GET)</p>
+<p>Excluding the internal-use-only the AM<->Agent channel operating on a private HTTP port, there are a number of current services</p>
+<h1 id="read-only-access-to-the-yarn-registry-wsv1sliderregistry">Read only access to the YARN registry: /ws/v1/slider/registry</h1>
+<p>This was done primarily to get a browseable view of what the YARN-913 registry was publishing in the absence of any web view built in to that registry. The unit tests against this service actually discovered some JSON marshalling problems with the registry design and Jersey integration. </p>
+<p>The root path <code>/v1/slider/registry</code> lists the root path of the registry; all entries below it follow the path in the registry. </p>
+<div class="codehilite"><pre><span class="o">/</span><span class="n">ws</span><span class="o">/</span><span class="n">v1</span><span class="o">/</span><span class="n">slider</span><span class="o">/</span><span class="n">registry</span><span class="p">:</span> <span class="p">{</span>"<span class="n">nodes</span>"<span class="p">:[</span>"<span class="n">services</span>"<span class="p">,</span>"<span class="n">users</span>"<span class="p">]}</span>
+</pre></div>
+
+
+<p>Every entry in the path serves an instance of <code>org.apache.slider.server.appmaster.web.rest.registry.PathEntryResource</code>; a list of child directory entries, and, if present, the Yarn registry service record at that path (<code>org.apache.hadoop.registry.client.types.ServiceRecord</code>).</p>

The slider client operations to enumerate and retrieve configuration files could use it, but they currently also use the YARN registry directly.</p>
+<p>As and when the YARN registry itself implements a REST view (possibly an R/W one), then this view will become obsolete âand possibly disabled.</p>
