Hadoop 连接在端口 9000 上被拒绝。VirtualBox 端口 9000 转发不适用于桥接适配器

Question

我在 VirtualBox Ubuntu 上安装了 Hadoop。所有端口都通过网桥适配器转发到 Windows。但是9000端口不可用。我已经禁用了 Windows Defender、Firewall 和 SmartScreen。

问题解决：端口转发到localhost

sudo sysctl -w net.ipv4.conf.all.route_localnet=1
sudo iptables -t nat -A PREROUTING -p tcp -d 192.168.0.12/24 --dport 9000 -j DNAT --to-destination 127.0.0.1:9000
sudo iptables -t nat -A POSTROUTING -j MASQUERADE

Hadoop 连接在端口 9000 上被拒绝。VirtualBox 端口 9000 转发不适用于桥接适配器

Hadoop connection refused on port 9000. VirtualBox port 9000 forwarding not working with Bridged adapter
