推荐答案

有几种不同的解决方案

1. 获取您的主机名

1. Get your hostname

$ hostname

然后尝试分配您的主机名

then try to assign your host name

$ sudo hostname -s 127.0.0.1

开始spark-shell.

将主机名添加到/etc/hosts文件中(如果不存在)

Add your hostname to your /etc/hosts file (if not present)

127.0.0.1      your_hostname

添加环境变量

Add env variable

export SPARK_LOCAL_IP="127.0.0.1" 

load-spark-env.sh 

以上步骤解决了我的问题，但您也可以尝试添加

Above steps solved my problem but you can also try to add

export SPARK_LOCAL_IP=127.0.0.1 

在模板文件spark-env.sh.template(/usr/local/Cellar/apache-spark/2.1.0/libexec/conf/)上的本地IP注释下

under the comment for local IP on template file spark-env.sh.template (/usr/local/Cellar/apache-spark/2.1.0/libexec/conf/)

然后

cp spark-env.sh.template spark-env.sh
spark-shell

如果以上均未解决，请检查您的防火墙并启用它(如果尚未启用)

If none of the above fixes, check your firewall and enable it, if not already enabled
