Hadoop异常处理 Bad connect ack with firstBadLink (No route to host )

同时添加几十个新节点之后

用hive执行测试语句报大量的错误：

[INFO]ExceptionincreateBlockOutputStreamjava.io.IOException:

java.io.IOException: Bad connect ack with firstBadLink as 192.168.1.178:50010
Continuing ...
java.io.IOException: Bad connect ack with firstBadLink as 192.168.1.178:50010
Continuing ...

add_log:

DataXceiver:java.net.NoRouteToHostException:Noroutetohost

另外集群开启的balance

blks 也没有同步到新的节点

解决办法：

root用户关闭防火墙 service iptables stop
