每当我在本地计算机上运行 start-master.sh 命令时，我会收到以下错误，请有人帮我解决此问题

终端错误

我在终端

中遇到的错误

starting org.apache.spark.deploy.master.Master, logging to /usr/local/spark-2.0.1-bin-hadoop2.6/logs/spark-andani-org.apache.spark.deploy.master.Master-1-andani.sakha.com.out

记录错误

如果我检查以下火花日志文件是错误

Exception in thread "main" java.net.BindException: Cannot assign requested address: Service 'sparkMaster' failed after 16 retries! Consider explicitly setting the appropriate port for the service 'sparkMaster' (for example spark.ui.port for SparkUI) to an available port or increasing spark.port.maxRetries.

错误是由于您的sparkMaster无法与您的内部IP联系

• 检查/ etc / hosts文件后，它指向正确的主机名，或者您之前的IP地址可能已更改。
• 重新配置它并再次运行命令。
