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
