How far into the installation did you get?
There is an uninstall script on the CM server, but that won't uninstall the agents or Hadoop packages. Since you're using VM's, it might be fastest to re-install the OS or remove all the packages by hand on one of the data nodes and then clone the VM for the other nodes.
You can stop the Hadoop services by hard stopping the agents on all the nodes:
sudo /sbin/service cloudera-scm-agent hard_stop
and then you can kill any of the rouge java processes:
sudo killall java

If using CM API, please provide some examples . I need to remove the datanode process in my VM Instance and similarly in my other VMs.
Please help me.
Thanks,

Hi All,
I had installed CDH4 using cloudera manager. I did several changes that nothing seems to be working right now. So I want to unistall everything and start the process a fresh.
I had installed in 8 VMs . I need to unistall everything.
I don't have access to the admin console and hence it is not possible for me to stop the services from there. Please provide command line options to unistall the whole set up across the 8 VMs.
Thanks,
Ranjani
