hdfs报错:There are 0 datanode(s) running and 0 node(s) are excluded in this operation

namenode的日志还是打印There are 0 datanode(s) running and 0 node(s) are excluded in this operation.吗

 

报错信息如下所示。其中,【X】是当前正在运行的DataNode数量,【Y】是被排除在此操作之外的DataNode数量。

问题原因

该问题表示在当前的集群状态下,因为无法满足文件的最小副本数量,HDFS无法将文件写入到指定路径中。
