1、虽然，不是大错，还说要贴一下，由于我运行run-example streaming.NetworkWordCount localhost 9999的测试案例，出现的错误，第一感觉就是Spark没有启动导致的：
// :: ERROR SparkContext: Error initializing SparkContext.

2、启动Spark的脚本命令：
[hadoop@slaver1 spark-1.5.1-bin-hadoop2.4]$ sbin/start-all.sh
[hadoop@slaver2 ~]$ run-example streaming.NetworkWordCount localhost 9999
