<p>The Spark Streaming receiver for Pulsar is a custom receiver that enables Apache <a href="https://spark.apache.org/streaming/">Spark Streaming</a> to receive raw data from Pulsar.</p>
<p>An application can receive data in <a href="https://spark.apache.org/docs/latest/programming-guide.html#resilient-distributed-datasets-rdds">Resilient Distributed Dataset</a> (RDD) format via the Spark Streaming receiver and can process it in a variety of ways.</p>

<p>For a complete example, click <a href="https://github.com/apache/pulsar-adapters/blob/master/examples/spark/src/main/java/org/apache/spark/streaming/receiver/example/SparkStreamingPulsarReceiverExample.java">here</a>. In this example, the number of messages that contain the string &quot;Pulsar&quot; in received messages is counted.</p>
<p>Note that if needed, other Pulsar authentication classes can be used. For example, in order to use a token during authentication the following parameters for the <code>SparkStreamingPulsarReceiver</code> constructor can be set:</p>
<pre><code class="hljs css language-java">SparkStreamingPulsarReceiver pulsarReceiver = <span class="hljs-keyword">new</span> SparkStreamingPulsarReceiver(
        serviceUrl,
