According to documenation:
http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-replication-issues.html

When setting up circular replication for clusters with different
SQL nodes in each cluster used as replication master and slave,
SQL nodes must not start with --log-slave-updates option. 

This patch fixed the test case by remove log-slave-updates 
configuration from test case configuration file.
