Description

In my Ubuntu 18.04 dev VM, I cloned the hadoop repo and ran the start-build-env.sh script.  Once the docker build was completed and the container running, I tried to sudo and it failed.  Upon investigation, I discovered that it was creating an entry in /etc/sudoers.d/hadoop-build-${USER_ID} that contained the characters '\t' rather than a tab.
