Hi All- I did some chmod/chown changes on all and since then I am not able to login with root user. sudo command is not working. Tried all the options available online, still getting this error- "sudo: effective uid is not 0, is sudo installed setuid root?" I know that the uid for the file /usr/bin/sudo must be set to 0 but currently it is 1 and i am not able to change it.   As soon as I launch the VM it opens with user "cloudera" by default. Is there any way to launch the VM with root user? Anyone know if this can be fixed while restarting the VM?   Just want to fix this without re-installing the complete VM. Thanks, appreciate any help/insights on this. ... View more
