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?
