使用hadoop上传文件 hdfs dfs -put XXX

查看hadoop是否正常,进程是否完整
查看磁盘使用情况
从这里可以看出操盘的空间都是空的
原因可能是hadoop格式化的时候出现了问题
然后将logs和tmp中的文件全部删除,重新格式化也没成功,后来看到clusterId不一致的问题
修改了VERSION文件中的clusterId随着又出现了 is in an inconsistent state的问题,
在hadoop-hdfs.xml中增加了
<property> <name>dfs.name.dir</name> <value>/soft/hadoop/name</value> #hadoop的name目录路径 </property> <property> <name>dfs.data.dir</name> <value>/soft/hadoop/data</value> #hadoop的data目录路径 </property>
重新格式化然后启动就可以了。
陆陆续续折腾了一上午、、、
以上是关于大数据系列hadoop上传文件报错_COPYING_ could only be replicated to 0 nodes的主要内容,如果未能解决你的问题,请参考以下文章
hadoopmaster主机上传文件出错: put: File /a.txt._COPYING_ could only be replicated to 0 nodes instead of minR
Hadoop dfs put 创建 _COPYING_ 暂存文件
hadoop全分布式集群搭建好了,每台机器启动的节点也正确,但是就是不能上传本地文件,报错:
Hadoop上传文件时报错: could only be replicated to 0 nodes instead of minReplication (=1)....
