I have a Windows running a CentOS6 (32-bit) on a VMWare virtual machine. I am attemping to install a single-node Cloudera Hadoop according to these instructions.  At one point I was asked to issue for x in `cd /etc/init.d ; ls hadoop-hdfs-*` ; do sudo service $x start ; doneand I received the following error:ls: cannot access hadoop-hdfs-*: No such file or directoryWhen I cd into my /etc/ directory, and issue ls, I receive the following:ls: reading directory .: Input/output errorFrom googling I learned that the ls: reading directory .: Input/output error can occur when hardware is failing. I don't think that is related to my problem, because the /etc/ directory is the only place where I cannot issue an ls, plus I am on a virtual machine with a new computer.df -hproduces
When issuing ls in the /etc/ directory, I get ls: reading directory .: Input/output error
ls;etc
