知道为什么我会收到此错误吗？10.0.1.193是我的从属虚拟机之一。

ubuntu@anmol-vm1-new:/home/hadoop/yarnpp$ hadoop fs -put tez-0.4.1-incubating/* /apps/tez-0.4.1-incubating

看起来防火墙正在阻止数据节点的流量。在 datanode 机器上打开以下端口（在您的情况下为 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
