What can I check to resolve this issue? Had someone changing stuff and have no idea what they did to kill my hadoop cloudera.

If there was some changes to the MapReduce or Yarn service, you can see those configuration changes by hitting the "History and Rollback" button on the configuration page for the service. That will display the most recent changes, and you can review those and rollback if needed.
