Description:
We have a Master Slave MySQL cluster.. Master Mysql cluster has 2 nodes and Slave MySQL Cluster also has 2 servers.
We are using Mysql version as 5.6.20 and NDB version is 7.3.6
When the replication is initiated, on my slave MySQL Cluster I observe following messages in my mysql error file:-
2015-06-26 10:13:48 2731 [Note] Error reading relay log event: slave SQL thread was killed 2015-06-26 10:13:48 2731 [ERROR] Error reading packet from server: Lost connection to MySQL server during query ( server_errno=2013) 2015-06-26 10:13:48 2731 [Note] Slave I/O thread killed while reading event 2015-06-26 10:13:48 2731 [Note] Slave I/O thread exiting, read up to log 'mysql-bin.000059', position 129077943 2015-06-26 10:13:48 2731 [Note] 'CHANGE MASTER TO executed'.

On further googling i found this is an existing issue and for this I also applied following three parameters in the my.cnf relay-log-recovery = 1 relay-log-info-repository = TABLE master_info_repository = TABLE
After this i restarted my mysql and performed START SLAVE as well. Still this issue exists.
Please share the solution or pointers to proceed further
How to repeat:
This is a recursive behavior which is seen on the Slave servers.
