      Description

      When ConnectorContext has a null value, the following code throws NPE:

      MapReduceSubmissionEngine.java
          // Serialize connector context as a sub namespace
          for(Map.Entry<String, String> entry :request.getConnectorContext()) {
            configuration.set(
              JobConstants.PREFIX_CONNECTOR_CONTEXT + entry.getKey(),
              entry.getValue());
          }
      

      The call stack looks like this:
