MySQL 5.5 to RDS 5.6 Replication Error
This is due to MySQL Master and Slave version mismatch

The message below is clear, and confirms the master/slaves run different versions. The variable SERVER_UUID is not supported with MySQL 5.5 but is supported with MySQL 5.6

2015-06-29 11:01:01 8026 [Warning] Slave I/O: Unknown system variable 'SERVER_UUID' on master. A probable cause is that the variable is not supported on the master (version: 5.5.41-0ubuntu0.12.04.1-log), even though it is on the slave (version: 5.6.22-log), Error_code: 1193
