> Noticed the Nullpointer exception when we put one of the host in maintenance
> mode
> Steps:
> 1.Configured cluster management setup with 4 management server and 4
> hosts(make sure each host was managed by unique Ms )
> 2.create few domain and user accounts
> 3 login with that account and deploy vms based on isolated and sharednetworks
> 4.once the all the vms are up and running
> 5.select one host and put in maintenance mode
> actual result;
> Putting the one of host into maintenance mode causes the
> java.lang.NullPointerException.
