String nodeURL;
@BeforeTest
public void draganddrop() throws MalformedURLException
{
    // driver = new FirefoxDriver();
    System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.Jdk14Logger");
    nodeURL = "http://localhost:4444/wd/hub";
    DesiredCapabilities cap = new DesiredCapabilities();

WebElement DragFrom = driver.findElement(By.xpath("//*[@id='dragdiv']"));
WebElement DragTo = driver.findElement(By.xpath("//*[@id='dropdiv']"));

    Actions builder = new Actions(driver);
    Action dragAndDrop3 =  builder.dragAndDrop(DragFrom, DragTo).build();
    dragAndDrop3.perform();

    String Texttocompare = driver.findElement(By.xpath("//*[@id='Blog1']/div[1]/div/div/div/div[1]/h3")).getText();

Try this and it might work

Actions actionsBuilder = new Actions(driver);
builder.keyDown(Keys.CONTROL)
   .click(elementName)
   .keyUp(Keys.CONTROL);
Action action = actionsBuilder.build();
action.perform();   

Not sure why drag and drop isn't working for you. If you're running multi threads in your nodes try running with just tone thread. Also it's worth mentioning your node OS information.
