Remove "innodb_additional_mem_pool_size" setting from my-innodb-heavy-4G.cnf file

After installing 10.2 on my CentOS 7 box, I copied over the sample config file

/usr/share/mysql/my-innodb-heavy-4G.cnf

to

/etc/my.cnf.d/

, while server failed to start with error.

Removing the

innodb_additional_mem_pool_size

setting from the sample config would resolve the issue.
