sparkDriver请求地址失败

Question

在我的终端上运行pyspark时，pyspark initiation中出现了一个新问题：

17/12/28 10:31:59 ERROR SparkContext: Error initializing SparkContext. java.net.BindException: Can't assign requested address:

Service 'sparkDriver' failed after 16 retries (starting from 0)! Consider explicitly setting the appropriate port for the service 'sparkDriver' (for example spark.ui.port for SparkUI) to an available port or increasing spark.port.maxRetries.

我一开始以为是Java运行时的问题，但事实并非如此，spark驱动程序无法连接到主机。 有什么想法吗？帮忙吗？建议？在
