<h1>Proxy</h1> + + <h2 id="proxy">Proxy</h2> + +<p>The proxy API allows the interaction with Accumulo with languages other than Java. +A proxy server is provided in the codebase and a client can further be generated. +The proxy API can also be used instead of the traditional ZooKeeperInstance class to +provide a single TCP port in which clients can be securely routed through a firewall, +without requiring access to all tablet servers in the cluster.</p> + +<h3 id="prerequisites">Prerequisites</h3> + +<p>The proxy server can live on any node in which the basic client API would work. That +means it must be able to communicate with the Master, ZooKeepers, NameNode, and the +DataNodes. A proxy client only needs the ability to communicate with the proxy server.</p> + +<h3 id="configuration">Configuration</h3> + +<p>The configuration options for the proxy server live inside of a properties file. At +the very least, you need to supply the following properties:</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>protocolFactory=org.apache.thrift.protocol.TCompactProtocol$Factory +tokenClass=org.apache.accumulo.core.client.security.tokens.PasswordToken +port=42424 +instance=test +zookeepers=localhost:2181 +</code></pre> +</div> + +<p>You can find a sample configuration file in your distribution at <code class="highlighter-rouge">proxy/proxy.properties</code>.</p> + +<p>This sample configuration file further demonstrates an ability to back the proxy server +by MockAccumulo or the MiniAccumuloCluster.</p> + +<h3 id="running-the-proxy-server">Running the Proxy Server</h3> + +<p>After the properties file holding the configuration is created, the proxy server +can be started using the following command in the Accumulo distribution (assuming +your properties file is named <code class="highlighter-rouge">config.properties</code>):</p> + +<div class="highlighter-rouge"><pre class="highlight"><code>accumulo proxy -p config.properties +</code></pre> +</div> + +<h3 id="creating-a-proxy-client">Creating a Proxy Client</h3> + +<p>Aside from installing the Thrift compiler, you will also need the language-specific library +for Thrift installed to generate client code in that language. Typically, your operating +systemâs package manager will be able to automatically install these for you in an expected +location such as <code class="highlighter-rouge">/usr/lib/python/site-packages/thrift</code>.</p> + +<p>You can find the thrift file for generating the client at <code class="highlighter-rouge">proxy/proxy.thrift</code>.</p> + +<p>After a client is generated, the port specified in the configuration properties above will be +used to connect to the server.</p> + +<h3 id="using-a-proxy-client">Using a Proxy Client</h3> + +<p>The following examples have been written in Java and the method signatures may be +slightly different depending on the language specified when generating client with +the Thrift compiler. After initiating a connection to the Proxy (see Apache Thriftâs +documentation for examples of connecting to a Thrift service), the methods on the +proxy client will be available.
