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.
> start-build-env.sh creates an invalid /etc/sudoers.d/hadoop-build-${USER_ID}
> file entry

> Key: HADOOP-15802
> URL: https://issues.apache.org/jira/browse/HADOOP-15802
> Project: Hadoop Common
> Issue Type: Bug
> Components: common
> Environment: Ubuntu 18.04 x86_64 running in a VM with 4 CPUs / 8 GBs
> RAM / 128 GB disk.
> Reporter: Jon Boone
> Priority: Minor
>
> 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.
