> - Right after clicking Next on AssignMasters Page there comes a popup in 
> AssignSlaves page that there is an issue with slaves assignment (pic1.png)
> - Click Cancel on warning and check the details. Issue was:
> {code}
> At least 1 NodeManager components should be installed in cluster.
> {code}
> Try to choose NodeManager checkbox. But its disabled. User can still proceed 
> by clicking Next and Continue Anyway. But the issue showed in popup and 
> NodeManager checkbox being disabled doesnt look right
> Could you please take a look at this scenario
