File /user/cuichunchi/hadoop/NOTICE.txt._COPYING_ could only be replicated to 0 nodes instead of minReplication (=1). There are 3 datanode(s) running and 3 node(s) are excluded in this operation.
上傳文件到hadoop分佈式文件系統中出現報錯:如下
解決問題:
第一將 tmp臨時文件下的hadoop文件都刪除。
然後重新執行hadoop namenode -format格式化下,之後執行腳本start-all.sh。
第二 :將每臺的防火牆關閉:
查看防火牆: systemctl status firewalld
關閉:systemctl stop firewalld 或者直接iptables -F即可
