python - Hadoop 错误：_COPYING_ 只能复制到 0 个节点而不是 minReplication (=1)

Question

我正在尝试在安装了 hdfs 的 ubuntu18 中执行以下命令。请帮忙。

hadoop fs -put /home/root-sai/Downloads/sample.txt /RBI

错误：

put: File /RBI/sample.txt._COPYING_ could only be replicated to 0 nodes instead of minReplication (=1).  There are 0 datanode(s) running and no node(s) are excluded in this operation.
