# 文件错误导致上传文件到HDFS失败
#### 问题描述
用**hadoop dfs -put**把本地文件拷贝到HDFS上，有报错。
上传部分文件后，报错失败，从NameNode原生页面看，临时文件大小不再变化。
#### 原因分析
1. 查看NameNode日志"/var/log/Bigdata/hdfs/nn/hadoop-omm-namenode-主机名.log"，发现该文件一直在被尝试写，直到最终失败。

2. 根因分析：被上传的文件损坏，因此会上传失败。
3. 验证办法：cp或者scp被拷贝的文件，也会失败，确认文件本身已损坏。
 
#### 处理步骤
1. 文件本身损坏造成的此问题，采用正常文件进行上传。
