Replication from MySQL 5.0 to MariaDB 10.2.8 - Unknown system variable 'binlog_checksum', Internal MariaDB error code: 1193
I found the solution/workaround. I need to set the variable slave_sql_verify_checksum=0 on the slave (MariaDB 10.2.8). I was trying this by dynamically setting the global variable on the slave but it wasn't working. Then I found bug #MDEV 8505 which indicates that resetting the variable dynamically does not work. Once I set it in the my.cnf and restarted the instance, everything started working as expected. Thankfully this is only a interim solution until we complete the upgrade!
