将本地文件上传到HDSF ,结果文件传输到半截，报了一个错误：

Name node is in safe mode

Resources are low on NN. Please add or free up more resources then turn off safe mode manually. NOTE:  If you turn off safe mode before adding resources, the NN will immediately return to safe mode. Use "hdfs dfsadmin -safemode leave" to turn safe mode off.
