>    Affects Versions: 1.4.3

> Steps to reproduce:
> Run Ambari installer UI.
> Provide wrong private key
> Register Hosts
> Expected 
> Message about wrong SSH key
> Actual 
> Installation freezes for long time. If you click on host link, you can see:
> STDERR
> Permission denied (publickey,gssapi-with-mic,password).
> lost connection
> scp /usr/lib/python2.6/site-packages/ambari_server/os_type_check.sh done for host c5901.ambari.apache.org, exitcode=1
> Copying os type check script finished.
> And there is no obvious way to interrupt that process. It seems that it lasts forever. I think UI must have some message about whats wrong, and ability to interrupt registering process if something goes wrong.
> I have tried to workaround this problem by deleting this hosts and going back to step 3. If I do that way in first few minutes, messagebox appears (see screenshot attached). I think it is not expected behaviour. After a few(aprox 5 or more) minutes, it is possible to delete hosts, go to step 3 and retry.
