Can I add a new method to RDD class?

[tenglong]

Hi,

Apparently, I've already tried adding a new method to RDD,

for example,

class RDD {
  def foo() // this is the one I added

  def map()

  def collect()
}

I can build Spark successfully, but I can't compile my application code
which calls rdd.foo(), and the error message says

value foo is not a member of org.apache.spark.rdd.RDD[String]

So I am wondering if there is any mechanism prevents me from doing this or
something I'm doing wrong?
