Hadoop,Hbase,nutch搭建过程遇到的问题

问题如下：在使用Nutch进行抓取的时候，程序卡在Injection urlDir下面不向下走了，查看nutch下面的hadoop.log没有报任何错误。

查看 Hbase 文件logs日志下的Hmaster日志有如下错误

网上说这个错误跟Hadoop的namenode节点相关，有打开hadoop下面的logs目录，发现报错如下，虽然使用JPS查看namenode进程是存在的：

试过了所有网上的方式，重新格式化namenode，修改host，最后发现是自己的系统硬盘空间不足，所以无法向namenode写入数据。

查看硬盘命令：df -h
