[#MCOL-5011] Wrong capitalisation in Columnstore cmapi rpm preuninstall script

The preuninstall script for CentOS7 MariaDB-columnstore-cmapi-1.5.x86_64.rpm has a typo that stops the package from being removed. The service name in the preuninstall script doesn't exist:

Failed to stop MariaDB-columnstore-cmapi.service: Unit MariaDB-columnstore-cmapi.service not loaded.

Failed to execute operation: No such file or directory

error: %preun(MariaDB-columnstore-cmapi-1.5-1.x86_64) scriptlet failed, exit status 1

Error in PREUN scriptlet in rpm package MariaDB-columnstore-cmapi-1.5-1.x86_64

The servicename should be "mariadb-columnstore-cmapi" not "MariaDB-columnstore-cmapi" (note capitalisation):

rpm -qp --scripts MariaDB-columnstore-cmapi-1.5.x86_64.rpm

pretrans program: /bin/sh

preinstall program: /bin/sh

postinstall scriptlet (using /bin/sh):

#!/usr/bin/env bash

systemctl enable mariadb-columnstore-cmapi

systemctl start mariadb-columnstore-cmapi

preuninstall scriptlet (using /bin/sh):

#!/usr/bin/env bash

systemctl stop MariaDB-columnstore-cmapi

find /usr/share/columnstore/cmapi -type d -name __pycache__ -print0 | xargs --null --no-run-if-empty rm -rf

systemctl disable MariaDB-columnstore-cmapi

Copying the service to the name it's looking for and then attempting a yum remove works:

cp /usr/lib/systemd/system/mariadb-columnstore-cmapi.service /usr/lib/systemd/system/MariaDB-columnstore-cmapi.service

yum remove MariaDB-columnstore-cmapi

rm /usr/lib/systemd/system/MariaDB-columnstore-cmapi.service
