             Summary: Ambari host registering freezes if wrong ssh key provided.
                 Key: AMBARI-4163
                 URL: https://issues.apache.org/jira/browse/AMBARI-4163
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.4.3
            Reporter: Myroslav Papirkovskyy
            Assignee: Myroslav Papirkovskyy
             Fix For: 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.
