With 2 NDB and 2 MySQL running no ISSUE

My Issue here is

1. I have stop 1 NDB, (lets say id=2 @192.168.0.112) and 2 MySQL are running.
a. I have done some transactions like Insert, update.

2. Now i have Stop another NDB, (id=3 @192.168.0.200) and 2 MySQL are running.
a. When i try to reterive the data which was insert or update on another node (Refer: Point 1) is not showing up.
b. I have done one more test, with same NDB started (id=3 @192.168.0.200) with two MySQL, inserted some records.

3. Stopped NDB Node (id=3 @192.168.0.200) and Started NDB Node (id=2 @192.168.0.112)
a. The records which we have in Step 2 are not displaying on this node.
