1：启动Spark Shell，spark-shell是Spark自带的交互式Shell程序，方便用户进行交互式编程，用户可以在该命令行下用scala编写spark程序。
启动Spark Shell，出现的错误如下所示：

2：解决方法，是你必须先启动你的Spark集群，这样再启动Spark Shell即可：
在master节点，启动你的spark集群，启动方式如下所示：
[root@master spark-1.6.1-bin-hadoop2.6]# sbin/start-all.sh
然后再启动你的Spark Shell即可，解决上面的错误：
[root@master spark-1.6.1-bin-hadoop2.6]# bin/spark-shell --master spark://master:7077 --executor-memory 512M --total-executor-cores 2
启动的内容，注意一些重点内容：
第33行，第47行，第119行。
[root@master spark-1.6.1-bin-hadoop2.6]# bin/spark-shell --master spark://master:7077 --executor-memory 512M --total-executor-cores 2
