Hi @SandyCT, well, this system is broken a bit more than I expected, since owner of groups is also damaged. What did you run exactly? If I had to guess, some recursive chmod on /, or /etc? Before you try this last option, try switching to console (ctrl+alt+F1 on a normal pc, not sure about the vm), and logging in as root, with password "cloudera". If this does not work, for whichever reason, here's a way to reboot Centos 6 in "safe mode". I suggest you make a backup of the whole vm file/directory first. https://lintut.com/reset-forgotten-root-password-in-centos/ If this does not work (I cannot test now, since I don't have my vm around), replace " 1 " in the tutorial with "rw init=/bin/bash" In either case, this will grant you root, but fixing your vm might take a while. For example, your sudo command should be "---s--x--x", or something to that regard, /etc/sudoers "-r--r-----", and "/etc/group" -rw-r--r--. Have fun & good luck! 🙂 ... View more

I've discovered by painful experience that this might be caused by having more than one oracle java installed, and even worse, any version of openjdk java. Namely, make sure you have added the ca you used for the ssl to the java keystore of the java version you are using (you can find that out in process list). Also, make sure that keytool you are using is belonging to this version of java - so it's best to have only one version installed, or (if that is unavoidable), use the full path to keytool. Hope it helps. ... View more
