LGTM.

It worked on CentOS 7:

$ ./docker-hadoop.sh \
    --create 1 \
    --image bigtop/puppet:trunk-centos-7 \
    --memory 16g \
    --enable-local-repo \
    --disable-gpg-check \
    --stack hdfs,yarn,mapreduce

yum-plugin-priorities is not provided on CentOS 8 since dnf itself provides the functionality.

Docker provisioner works even with the Error: Unable to find a match: yum-priorities error.

$ ./docker-hadoop.sh \
    --create 1 \
    --image bigtop/puppet:trunk-centos-8 \
    --memory 16g \
    --enable-local-repo \
    --disable-gpg-check \
    --stack hdfs,yarn,mapreduce
...
No match for argument: yum-priorities
Error: Unable to find a match: yum-priorities

same for Fedora 33.

$ ./docker-hadoop.sh \
    --create 1 \
    --image bigtop/puppet:trunk-fedora-33 \
    --docker-compose-yml docker-compose-cgroupv2.yml \
    --memory 16g \
    --enable-local-repo \
    --disable-gpg-check \
    --stack hdfs,yarn,mapreduce
...
No match for argument: yum-priorities
Error: Unable to find a match: yum-priorities
...

$ ./docker-hadoop.sh --exec 1 yum list 'hadoop'
