title: Spark Parallelize? (Could not find creator property with name 'id')
body: <p>What causes this Serialization error in Apache Spark 1.4.0 when calling:</p>
  
  <pre><code>sc.parallelize(strList, 4)
  </code></pre>
  
  <p>This exception is thrown:</p>
  
  <pre><code>com.fasterxml.jackson.databind.JsonMappingException: 
  Could not find creator property with name 'id' (in class org.apache.spark.rdd.RDDOperationScope)
  </code></pre>
  
  <p>Thrown from <code>addBeanProps</code> in <strong>Jackson</strong>: com.fasterxml.jackson.databind.deser.BeanDeserializerFactory#addBeanProps</p>
  
  <p>The RDD is a Seq[String], and the #partitions doesn't seem to matter (tried 1, 2, 4).</p>
  
  <p>There is no serialization stack trace, as normal the worker closure cannot be serialized.</p>
  
  <p>What is another way to track this down?</p>
