我在下面写了简单的spark程序，使用spark的StreamingContext和SQLContext。Apache Spark：线程驱动心跳中的未捕获异常
注意：即使没有streamingContext，问题也是可重复的。更新程序以反映相同。
注意：将spark版本降级到1.4.1（我使用的是1.5.2）似乎已经解决了我的问题。火花也是1.5.1这个问题我们可以重现。
def main(args: Array[String]) {
val sc = new SparkContext("local[*]", "test")
val sqc = new SQLContext(sc)
val dataFrame = sqc.read.json(sc.textFile("<dir>"))
println(dataFrame.groupBy("Product.SerialNumber").count().count())
sc.stop()
}
这是在开始时给出以下例外但执行正在进行并打印结果。
