title: Remove debug log from Console using Spark 1.6.2
body: <p>Using Java, I start a basic Spark app using:</p>
  
  <pre><code>    SparkConf conf = new SparkConf().setAppName("myApp").setMaster("local");
      JavaSparkContext javaSparkContext = new JavaSparkContext(conf);
      javaSparkContext.setLogLevel("INFO");
      SQLContext sqlContext = new SQLContext(javaSparkContext);
  </code></pre>
  
  <p>I try to have the system a little less verbosy by adding the <code>setLogLevel</code>, but it does not take it. I still have a lot of Debug information.</p>
  
  <p>Ideally, I would like to shut off all <code>org.apache.spark.*</code> except errors...</p>
  
  <p><strong>Update #1:</strong></p>
  
  <p>Here is my pom.xml:</p>
  
  <pre><code>&lt;dependencies&gt;
      &lt;dependency&gt;
          &lt;groupId&gt;mysql&lt;/groupId&gt;
          &lt;artifactId&gt;mysql-connector-java&lt;/artifactId&gt;
          &lt;version&gt;5.1.6&lt;/version&gt;
      &lt;/dependency&gt;
      &lt;dependency&gt;
          &lt;groupId&gt;org.hibernate&lt;/groupId&gt;
          &lt;artifactId&gt;hibernate-core&lt;/artifactId&gt;
          &lt;version&gt;5.2.0.Final&lt;/version&gt;
      &lt;/dependency&gt;
      &lt;dependency&gt;
          &lt;groupId&gt;org.apache.spark&lt;/groupId&gt;
          &lt;artifactId&gt;spark-core_2.10&lt;/artifactId&gt;
          &lt;version&gt;1.6.2&lt;/version&gt;
      &lt;/dependency&gt;
