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

最佳答案
看起来防火墙正在阻止到数据节点的流量。在数据节点机器上打开以下端口(在你的例子中是 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
关于java - createBlockOutputStream 中的异常 java.io.IOException : Bad connect ack with firstBadLink，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33990806/
