BTW, in Spark 1.4 announced today, I added SQLContext.getOrCreate. So you

First, you must check if the RDD is empty:
messages.foreachRDD { rdd =
if (!rdd.isEmpty) { }}
Now, you can obtain the instance of a SQLContext:
val sqlContext = SQLContextSingleton.getInstance(rdd.sparkContext)
Why? I tried this solution and works fine.
