Question

我试图通过在EC2实例（RHEL 7）中触发/sbin/start-all.sh来运行独立的Spark-2.1.1。每当它运行时，它都会询问root @ localhost的密码，即使给出了正确的密码也很难，它会引发我 - root@localhost's password: localhost: Permission denied, please try again.错误。

当我在控制台中点击jps时，无论出现此错误，我都可以看到Master正在运行。

root@localhost# jps 
27863 Master
28093 Jps

此外，我检查了日志，发现了这个 -

我试图弄清楚为什么我无法启动我的工作节点。有人可以帮我解决这个问题吗？感谢。

检查您的主机名是否正确解析。如果您使用的是localhost，请确保已在/etc/hosts文件中解析。

如果有帮助请告诉我。欢呼声。
