> If it is not considered to risky, it might be useful to prepare smoke tests 
> for testing NameNode High Availability. We use such tests a little in my 
> company (we have already implemented smoke tests that we can happily 
> contribute to)
> We test whether
> * Two NameNodes are running and one is in active state and one is in standby 
> state
> * We can do run a failover command successtully ($  haadmin ­failover 
> <toBe­Standby> <to­Be­Active­>)
> * Whether we can transition the active NN into standby state, and move back 
> to the active state.
