Hi,
The following WARN happens in Spark built from today's sources. There
were some changes about RPC so it may be related. Should I report an
issue in JIRA?
I use a sbt project and `sbt console` to play with Spark.
```
scala> import org.apache.spark.SparkConf
import org.apache.spark.SparkConf
scala> val conf = new
SparkConf().setMaster("local[*]").setAppName("Hello world!")
conf: org.apache.spark.SparkConf = org.apache.spark.SparkConf@7a8f69d6
scala> import org.apache.spark.SparkContext
import org.apache.spark.SparkContext
scala> val sc = new SparkContext(conf)
```
So far so good. After a while I can see my CPU going up and the REPL
shows up with the WARN:
```
