hdfs.DataStreamer: Exception in createBlockOutputStream XXXXX

报错信息:

java.io.IOException: Got error, status=ERROR, status message , ack with firstBadLink as 192.168.100.13:9866
	at org.apache.hadoop.hdfs.protocol.datatransfer.DataTransferProtoUtil.checkBlockOpStatus(DataTransferProtoUtil.java:134)

该报错比较简单,直观的看就是防火墙没关

参考:

随笔小记(查看和关闭防火墙、修改主机名、修改静态IP)

查看防火墙状态

firewall-cmd --state

停止firewall

systemctl stop firewalld.service

禁止firewall开机启动

systemctl disable firewalld.service 

开放指定端口

firewall-cmd --zone=public --add-port=1935/tcp --permanent

关闭指定端口

firewall-cmd --zone=public --remove-port=5672/tcp --permanent

重启防火墙

firewall-cmd --reloadl
