    Description

      When MariaDB is running, but mariadb-columnstore is not:

      systemctl stop mariadb-columnstore;
      

      Now, login to database and query:

      mariadb -s
      MariaDB [(none)]> select * from  information_schema.COLUMNSTORE_TABLES;
      ERROR 2013 (HY000): Lost connection to server during query
      MariaDB [(none)]>
      

      Database Error log includes: "[ERROR] mysqld got signal 6"
      Same will happen for any of these:

      select * from  information_schema.COLUMNSTORE_COLUMNS; 
      select * from  information_schema.COLUMNSTORE_TABLES;
      select * from  information_schema.COLUMNSTORE_FILES;
      select * from  information_schema.COLUMNSTORE_EXTENTS;
      

      A more graceful error without a restart of mariadb would be better.
