<p>This is intended to be a full two-way REST API offered by the Slider
Application
Master to clients. The draft design is <a

site</a>.</p>

+<p>The 0.70 release contains the foundational read-only view of this API.
+Look at the code in <code>org.apache.slider.client.rest</code>, in particular
+the API client, <code>SliderApplicationAPI</code>, and
<code>RestClientFactory</code> âwhich
+builds an instance of <code>SliderApplicationAPI</code> bonded to an
application located
+in the Zookeeper-based YARN registry.</p>
+<p>It is impossible
to offer a secure two-way REST API in Hadoop 2.6, due to how authentication and
security is implemented in the YARN Resource Manager proxy. Therefore even
though a two-way API is partially implemented in the slider code, it is
explicitly
read only. To enable it, set the property <code>slider.dev.ws.insecure</code>
to true in
the Slider Application Master. This can be done by setting it in the file
<code>$SLIDER_CONF_DIR/slider-server.xml</code>. </p>
