Then I read about an Emergency mode which is even lower level to that of Single User mode. I was able to log in and see the files that I created/modified as root. I could not see any file/folder that related the local user "cloudera" on which I used to work.
Just a wild guess...
Could it be possible that your /home, which contains all the files of the "cloudera" user, is located on a separate file system that does not automatically get mounted in emergency mode? That would at least explain why those files appear to be missing.
