Service ‘sparkDriver’ could not bind on a random free port. You may check whether configuring an appropriate binding address

本地测试 spark wordcount 时，报错如下：

参考 mac-spark-shell-error-initializing-sparkcontext。
执行hostname，拿到 hostname，然后编辑 /etc/hosts，添加如下行：

127.0.0.1     Your_Hostname

再次执行程序即ok。

I got the same error, which I manage to overcome by checking this https://superuser.com/questions/1436855/port-binding-error-in-pyspark
