知道我为什么会犯这个错误吗？ 10.0.1.193 是我的一个从属虚拟机。

看起来防火墙正在阻止数据节点的通信。打开datanode机器上的以下端口（本例中为10.0.0.193）。

-A INPUT -p tcp -m state --state NEW -m tcp --dport 50010 -m comment --comment "Port 50010  datanode" -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 50020 -m comment --comment "Port 50020  datanode" -j ACCEPT
