In the document https://mariadb.com/kb/en/library/preparing-for-columnstore-installation-11x (section "Initial download/install of MariaDB ColumnStore RPMs") the following command is mentioned:
"rpm -ivh mariadb-columnstore*release#*.rpm".

But it does not work for "mariadb-columnstore-1.1.5-1-centos7.x86_64.rpm.tar.gz" downloaded from https://downloads.mariadb.com/ColumnStore/1.1.5/centos/x86_64/7/ :
Output: "error: File not found by glob: mariadb-columnstore*release#*.rpm"

I have used "rpm -ivh mariadb-columnstore*.rpm" instead since the archive contains the following files:

mariadb-columnstore-1.1.5-1-x86_64-centos7-client.rpm
mariadb-columnstore-1.1.5-1-x86_64-centos7-common.rpm
