解决HDFS无法启动namenode，报错Premature EOF from inputStream；Failed to load FSImage file, see error(s) above for more info
一.情况描述
启动hadoop后发现无法打开hdfs web界面，50070打不开，于是jps发现少了一个namenode：
查看日志信息，发现如下报错：

二.解决方案
根据报错信息，发现是读取文件错误，后面即是文件路径名称，我这里是读取两个文件出错，然后删除日志中读取错误的文件（可以提前备份）
我这里已经删除了（.md5可以不删），之后重启hdfs，可以发现namenode已启动
重新进入hdfs页面
