Apache spark 无法启动Spark'；s"；全部启动。sh“；关于EC2（rhel7）

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，它都会请求root@localhost的密码，甚至很难。我已经给出了正确的密码，它会让我-

root@localhost的密码：localhost:权限被拒绝，请重试。

错误

当我在控制台中点击

jps

时，我可以看到主机正在运行

root@localhost# jps 
27863 Master
28093 Jps

我进一步检查了日志，发现了这个-

我正在试图找出我无法启动工作节点的原因。有人能帮我解决这个问题吗？谢谢。

检查主机名是否正确解析。 如果您使用的是

localhost

，请确保它已在

/etc/hosts

文件中解析

让我知道这是否有帮助。干杯。

我实际上使用的是系统ip地址，而不是“localhost”（出于安全原因刚刚重命名）。是的，主机名已正确解决，问题仍然存在。不过，请尝试在

/etc/hosts

文件中解决

localhost

，然后查看它是否有效，如下所示：

192.168.y.xxx主机名

192.168.y.xxx localhost

。如果是这样，则您必须更改属性

spark\u LOCAL\u IP

的spark conf（spark env.sh）。
