idea使用javaapi向hadoop上传文件时报错

我在使用本地idea向云服务器里的hadoop上传数据时报错：
org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /a.txt could only be replicated to 0 nodes instead of minReplication (=1). There are 1 datanode(s) running and 1 node(s) are excluded in this operation.

网上查过一些，大都是 There are 0 datanode(s) running and 0 node(s) are excluded in this operation.
而我的是， There are 1 datanode(s) running and 1 node(s) are excluded in this operation.
求问怎么解决
