MariaDB ColumnStore software upgrade 1.2.x GA to 1.2.5 GA    MariaDB ColumnStore software upgrade 1.2.x GA to 1.2.5 GA Changes in 1.2.1 and later libjemalloc dependency ColumnStore 1.2.3 onward requires libjemalloc to be installed. For Ubuntu & Debian based distributions this is installed using the package "libjemalloc1" in the standard repositories. For CentOS the package is in RedHat's EPEL repository: This does require either root user access or SUDO setup to install: sudo yum -y install epel-release
sudo yum install -y jemalloc

Non-distributed is the default distribution mode in postConfigure The default distribution mode has changed from 'distributed' to 'non-distributed'. During an upgrade, however, the default is to use the distribution mode used in the original installation. The options '-d' and '-n' can always be used to override the default. Non-root user sudo setup Root-level permissions are no longer required to install or upgrade ColumnStore for most types of installations. Installations requiring some level of sudo access, and the instructions, are listed here: https://mariadb.com/kb/en/library/preparing-for-columnstore-installation-121/#update-sudo-configuration-if-needed-by-root-user Running the mysql_upgrade script As part of the upgrade process to 1.2.5, the user is might be required to run the mysql_upgrade script on all of the following nodes. 1. If the system was upgraded to 1.1.x to 1.2.x. And now it being upgrade to 1.2.5, the mysql_upgrade script will need to be run. 2. If the system was initially installed with 1.2.x and now its being upgraded to 1.2.5, the mysql_upgrade script doesnt need to be run. So this section can be skipped. 
All User Modules on a system configured with separate User and Performance Modules

 mysql_upgrade should be run once the upgrade has been completed. This is an example of how it run on a root user install: /usr/local/mariadb/columnstore/mysql/bin/mysql_upgrade --defaults-file=/usr/local/mariadb/columnstore/mysql/my.cnf --force

This is an example of how it run on a non-root user install, assuming ColumnStore is installed under the user's home directory: $HOME/mariadb/columnstore/mysql/bin/mysql_upgrade --defaults-file=$HOME/mariadb/columnstore/mysql/my.cnf --force

In addition you should run the upgrade stored procedure below for a major version upgrade. Executing the upgrade stored procedure 1. If the system was upgraded to 1.1.x to 1.2.x. And now it being upgrade to 1.2.5, the upgrade stored procedure will need to be run. 2. If the system was initially installed with 1.2.x and now its being upgraded to 1.2.5, the upgrade stored procedure doesnt need to be run. So this section can be skipped. This updates the MariaDB FRM files by altering every ColumnStore table with a blank table comment. This will not affect options set using table comments but will erase any table comment the user has manually set. You only need to execute this as part of a major version upgrade. It is executed using the following query which should be executed by a user which has access to alter every ColumnStore table: call columnstore_info.columnstore_upgrade();

Upgrading from 1.2.4 to a later version Version 1.2.4 had a bug which caused bad metadata to be stored with dictionary columns. After an upgrade from 1.2.4 tables with dictionary columns (CHAR > 8 bytes, VARCHAR > 7, TEXT & BLOB) tables should be recreated and data cloned. This could be done using CREATE TABLE ... LIKE and using INSERT...SELECT. Setup In this section, we will refer to the directory ColumnStore is installed in as <CSROOT>. If you installed the RPM or DEB package, then your <CSROOT> will be /usr/local. If you installed it from the tarball, <CSROOT> will be where you unpacked it. Columnstore.xml / my.cnf Configuration changes made manually are not automatically carried forward during the upgrade. These modifications will need to be made again manually after the upgrade is complete. After the upgrade process the configuration files will be saved at: 
<CSROOT>/mariadb/columnstore/etc/Columnstore.xml.rpmsave 
<CSROOT>/mariadb/columnstore/mysql/my.cnf.rpmsave 
 MariaDB root user database password If you have specified a root user database password (which is good practice), then you must configure a .my.cnf file with user credentials for the upgrade process to use. Create a .my.cnf file in the user home directory, which is /root for root install and /home/'user' for non-root install. Set 600 as the file permissions with the following content (updating PASSWORD as appropriate): [mysqladmin]
user = root
password = PASSWORD

Choosing the type of upgrade Note, softlinks may cause a problem during the upgrade if you use the RPM or DEB packages. If you have linked a directory above /usr/local/mariadb/columnstore, the softlinks will be deleted and the upgrade will fail. In that case you will need to upgrade using the binary tarball instead. If you have only linked the data directories (ie /usr/local/MariaDB/columnstore/data*), the RPM/DEB package upgrade will work. Root User Installs Upgrading MariaDB ColumnStore using the tarball of RPMs (distributed mode) Upgrade MariaDB ColumnStore as user root on the server designated as PM1:  Download the package mariadb-columnstore-1.2.5-1-centos#.x86_64.rpm.tar.gz to the PM1 server where you are installing MariaDB ColumnStore.
