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? -- View this message in context: http://apache-spark-developers-list.1001551.n3.nabble.com/Can-I-add-a-new-method-to-RDD-class-tp20100.html Sent from the Apache Spark Developers List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe e-mail: dev-unsubscr...@spark.apache.org
