我安装了这个spark版本：spark-1.6.1-bin-hadoop2.6.tgz。
现在当我开始用 ./spark-shell 命令我得到这个问题（它显示了很多错误行，所以我只是把一些似乎很重要）

我尝试了一些配置来解决这个问题，我在有关值sqlcontext not found问题的其他问题中搜索了这些问题，例如：
/etc/hosts文件：

127.0.0.1  hadoophost localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    10.2.0.15 hadoophost
``` `echo $HOSTNAME` 退货：
Hadoop主机
.bashrc文件包含：

export SPARK_LOCAL_IP=127.0.0.1

但不工作，你能给一些帮助，试图了解为什么Spark没有启动正确？
