Slave: Got error 4009 'Cluster Failure' from NDB Error_code: 1296 [Warning] Slave: Can't lock file (errno: 157 - Could not connect to storage
engine) Error_code: 1015
Error running query, slave SQL thread aborted. Fix the problem, and
restart the slave SQL thread with &quot;SLAVE START&quot;.
In MySQL Cluster the MySQL server that handles the replication slave
will write into the NDB data nodes. Since the NDB Data nodes are
down it isn't possible to write into them and you get the above
mentioned errors. Replication will start up again when the data
nodes are up again and the slave SQL thread is restarted.
