文件上传异常信息

 org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /test1/renhh/test1.txt could only be written to 0 of the 1 minReplication nodes. There are 1 datanode(s) running and 1 node(s) are excluded in this operation.

Answer 1

datanode在运行但是有问题被排除掉了。看看datanode的日志检查下datanode有什么问题吧。
