> Currently, when a Namenode is in safemode(under starting or enter safemode 
> manually), we can transfer this Namenode to Observer by command. This 
> Observer node may receive many requests and then throw a SafemodeException, 
> this causes unnecessary failover on the client.
> So Namenode in safe mode should not be transfer to observer state.
