Cloudera hadoop:无法运行Hadoop fs命令,同时HBase无法在HDFS上创建目录？

我有6个节点的cloudera 5.0 beta集群启动并运行

但我无法使用命令查看hadoop HDFS的文件和文件夹

sudo -u hdfs hadoop fs -ls /

在输出中它显示linux目录的文件和文件夹.

虽然namenode UI显示文件和文件夹.

而在HDFS上创建文件夹时收到错误

sudo -u hdfs hadoop fs -mkdir /test
mkdir: `/test': Input/output error

由于此错误,hbase未启动并因以下错误而关闭:
