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 ; done

and I received the following error:

ls: cannot access hadoop-hdfs-*: No such file or directory

When I cd into my /etc/ directory, and issue ls, I receive the following:

ls: reading directory .: Input/output error

From 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 -h

produces

  • I/O error on a run-of-the-mill on-disk filesystem? I'd say your hardware is failing. – Gilles 'SO- stop being evil' Nov 19 '13 at 23:17
  • @Gilles so I'm running this on a VM on my new labtop. The host operating system is fine and I have never received and hardware failing errors. Do you know what could emulate this effect on a VM? – Matthew Moisen Nov 19 '13 at 23:26

Something is definitely up with your installation of CentOS and this VM. I would suspect that the options you've picked for the type of hardware that you want VMWare to emulate is the root of your issue.

The other thing I would check is that your VM has ample free diskspace. You can issue this command when inside the VM to determine the disk usage.

Example

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      429G  358G   49G  89% /
/dev/sda1              99M   33M   61M  36% /boot
tmpfs                 5.9G     0  5.9G   0% /dev/shm

  • Hi slm, would you look at my answer again? I was unable to run this command in the same environment. I decided to restart my virtual box which wiped the whole thing clean back to its original state. I've tried installing Hadoop again and got a different set of problems. But I'm still getting "input/output" errors. I made this VM take up 20g of hard disk space. – Matthew Moisen Nov 19 '13 at 22:41
  • @MatthewMoisen - can you explain why it says centos livecd? Are you trying to run the VM using a live distro? – slm♦ Nov 20 '13 at 1:36
