Description

Using create-release will create a docker image locally, but three of the RUN scripts may fail to execute.

1. RUN groupadd --non-unique -g 0 root

=> ERROR [16/20] RUN groupadd --non-unique -g 0 root                                                            0.2s
------
 > [16/20] RUN groupadd --non-unique -g 0 root:
0.154 groupadd: group 'root' already exists
------
Dockerfile:100
--------------------
  98 |
  99 |     LABEL org.apache.hadoop.create-release="cr-19697"
 100 | >>> RUN groupadd --non-unique -g 0 root
 101 |     RUN useradd -g 0 -u 0 -m root
 102 |     RUN chown -R root /home/root

2. RUN useradd -g 0 -u 0 -m root

 > [17/20] RUN useradd -g 0 -u 0 -m root:
0.165 useradd: user 'root' already exists
------
Dockerfile:101
--------------------
  99 |     LABEL org.apache.hadoop.create-release="cr-12068"
 100 |     RUN groupadd --non-unique -g 0 root; exit 0;
 101 | >>> RUN useradd -g 0 -u 0 -m root
 102 |     RUN chown -R root /home/root
 103 |     ENV HOME /home/root

3. RUN chown -R root /home/root

 > [18/20] RUN chown -R root /home/root:
0.168 chown: cannot access '/home/root': No such file or directory
------
Dockerfile:102
--------------------
 100 |     RUN groupadd --non-unique -g 0 root; exit 0;
 101 |     RUN useradd -g 0 -u 0 -m root; exit 0;
 102 | >>> RUN chown -R root /home/root
 103 |     ENV HOME /home/root
 104 |     RUN mkdir -p /maven
--------------------

Even if these three scripts fail, subsequent steps can continue to be executed, so I added exit 0 after the script.
