title: Twitter Popular Tags On Apache Spark
body: <p>I am new to apache spark. I was trying to run <a href="https://github.com/prabeesh/SparkTwitterAnalysis/tree/0.2.0" rel="nofollow">https://github.com/prabeesh/SparkTwitterAnalysis/tree/0.2.0</a> example but console is giving me the following error:</p>
  
  <pre><code> WARN scheduler.TaskSchedulerImpl: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient memory
  </code></pre>
  
  <p>I have started the server using <code>nc -lk 9999</code> and I have compiled the code by sbt/sbt package<br>
  and have excecuted the code using <code>sbt</code>/ <code>sbt 'run spark://localhost:9999 &lt;keys as specifies&gt; hashtag'</code></p>
  
  <p>What is the reason for this error and how to resolve it </p>
  
  <p>Thanks in advance.</p>
