当 my.cnf 中的 innodb 未注释时，MariaDB 列存储未启动

【中文标题】当 my.cnf 中的 innodb 未注释时，MariaDB 列存储未启动【英文标题】：MariaDB Columnstore not starting when innodb uncommented in my.cnf 【发布时间】：2019-03-18 03:51:10 【问题描述】：我在 Centos 7 上安装了 mariadb-columnstore-1.2.2-1-centos7.x86_64，单服务器安装，内部存储配置。运行 postConfigure 脚本时没有遇到任何错误，并且列存储数据库启动正常。
但是，当我取消注释 /usr/local/mariadb/columnstore/mysql/my.cnf 中的 innodb 参数并通过 mcsadmin 中的“stopSystem”和“startSystem”重新启动数据库时，服务器将无法启动，似乎是尝试启动 mysqld 时失败。重新注释掉 my.cnf 中的 innodb 参数，然后启动服务器工作正常。以下是我从 mcsadmin 控制台看到的错误以及错误日志。有没有其他人经历过类似的事情？非常感谢任何建议/见解！
* from the default my.cnf, the innodb parameters in question, uncommented that break the server startup:
# Uncomment the following if you are using InnoDB tables
innodb_data_home_dir = /usr/local/mariadb/columnstore/mysql/lib/mysql/
innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend
innodb_log_group_home_dir = /usr/local/mariadb/columnstore/mysql/lib/mysql/
innodb_log_arch_dir = /usr/local/mariadb/columnstore/mysql/lib/mysql/
# You can set .._buffer_pool_size up to 50 - 80 %
# of RAM but beware of setting memory usage too high
innodb_buffer_pool_size = 384M
innodb_additional_mem_pool_size = 20M
# Set .._log_file_size to 25 % of buffer pool size
innodb_log_file_size = 100M
innodb_log_buffer_size = 8M
innodb_flush_log_at_trx_commit = 1
innodb_lock_wait_timeout = 50

【问题讨论】：
【参考方案1】：有一个日志我忘记检查了：
/usr/local/mariadb/columnstore/mysql/db/db-01.err
有这个错误：
2019-03-18 12:30:13 139826114562176 [错误] /usr/local/mariadb/columnstore/mysql//bin/mysqld: 未知变量 'innodb_additional_mem_pool_size=20M'
innodb_additional_mem_pool_size 参数已弃用。
注释掉该参数可以解决问题。
