Subject [jira] [Commented] (HADOOP-15802) start-build-env.sh creates an invalid /etc/sudoers.d/hadoop-build-${USER_ID} file entry

    [ https://issues.apache.org/jira/browse/HADOOP-15802?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16648900#comment-16648900

Jon Boone commented on HADOOP-15802:
------------------------------------

My first thought was to add the '-e' option to the echo command being called in line 64:

??RUN echo "${USER_NAME}\tALL=NOPASSWD: ALL" > "/etc/sudoers.d/hadoop-build-${USER_ID}"??

as this command is running inside a docker container which is running Linux.

> 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.
