Review request for Ambari, John Speidel and Robert Nettleton.
Changes
-------
Fixed copy/paste issue
Bugs: AMBARI-9742
https://issues.apache.org/jira/browse/AMBARI-9742
Repository: ambari
Description
-------
Note: I don't believe the below is specific to add host, but related to the
prompting and how the set admin cred works in case of a blank password. I hit
this during testing of add host though.
- install cluster, kerberize
- add host (be sure to use a new browser so you know it will prompt for kerb
admin credentials)
- got to the review part of add host, click deploy
- prompted for admin creds (as expected)
- tried messing around by putting in bad creds and that seemed to work...
- expect when I put in the right admin cred principal name (admin/admin) but a
blank password. I was surprised it allowed me to click save (because the
password field was blank)
- so I click save, dialog disappears and I am cannot get it to re-prompt.
- this is what it PUT and the response was blank...
```
[{"session_attributes":{"kerberos_admin":{"principal":"admin/admin","password":""}}}]:

in ambari-server.log, nothing
```
17:58:05,860 INFO [qtp1257282095-603] AmbariManagementControllerImpl:1171 -
Received a updateCluster request, clusterId=2, clusterName=MyCluster,
securityType=null, request={ clusterName=MyCluster, clusterId=2,
provisioningState=null, securityType=null, stackVersion=HDP-2.2,
desired_scv=null, hosts=[] }
```
- back in wizard doesn't solve it. had to completely exit wizard and ambari web
to start again
The overall issue is how the credentials are being validated. If no password
is being set, the command to test the credentials when using a MIT KDC
generates the following command:
```
kadmin -p admin/admin -w "" -r EXAMPLE.COM -q 'get_principal admin/admin'
```
The empty password (`-w ""`) in the command creates an interactive session
where the command is waiting for data on STDIN, thus hanging the process.
An empty password should not cause the same behavior when using Active
Directory.
