title: SparkContext.loadFromMapRDB with generic type
body: <pre><code>def loadFromMapR[T: Manifest](path: String): RDD[T] = {
     val selectedTable = sc.loadFromMapRDB[T](path)
      selectedTable }
  </code></pre>
  
  <p>I am working in Scala and want to allow a generic type to be loaded from a SparkContext.  This code will work if I specify the type as such.</p>
  
  <pre><code>def loadFromMapR(path: String): RDD[basicObject] = {
    val selectedTable = sc.loadFromMapRDB[basicObject](path)
    selectedTable }
  </code></pre>
  
  <p>But I want to make it generic! My first code doesn't compile! I am getting an error that states: </p>
  
  <pre><code>not enough arguments for method loadFromMapRDB (implicit evidence $1: Scala.reflect.ClassTag[T])
  could not find implicit value for parameter f: com.mapr.db.spark.RDD.RDDTYPE[T]
  </code></pre>
  
  <p>Thanks!</p>
