Kerberos configs page Can't open

Explorer

Hi

I'm using AMBARI-2.1.2。 After complete the full intallation,I disabled Kerberos, and then enable Kerberos。 Services runs fine, But kerberos configs page can't open。

After debug with Chrome, I find some js error in app.js。

if (this.get('content.serviceName') === 'KERBEROS') {

var kdc_type = configs.findProperty('name', 'kdc_type');

if (kdc_type.get('value') === 'none') { //line 22515

At line 22515, there is a "Uncaught TypeError: Cannot read property 'get' of undefined"

And I find "kdc_type = undefined, configs = []", I think he problem is caused by "kdc_type = undefined"

I find there is no service:"KERBEROS" in http://hdp23:8080/api/v1/clusters/hdp23/configurations/service_config_versions

Any suggestion will be appreciated. Thanks.

Re: Kerberos configs page Can't open

There is a similar issue in our database of issues. Can you follow this:

Manually add the kerberos-env/kdc_type property back to the current kerberos-env configuration. The value must be either "mit-kdc" or "active-directory" and must be the correct one for the configuration. Once this is done, Ambari should be restarted so that any cached configuration data is refreshed. (This can be done with configs.sh command).

/var/lib/ambari-server/resources/scripts/configs.sh -u AMBARI_USER -p AMBARI_PASS set hdp23 hdp23 kerberos-env kdc_type "<kdc_type_value>"

@Orlando Teixeira

Thanks for your reply.

But I find there is already a kdc_type property in

/var/lib/ambari-server/resources/common-services/KERBEROS/1.10.3-10/configuration/kerberos-env.xml

And when I run commond "

/var/lib/ambari-server/resources/scripts/configs.sh -u admin -p admin set hdp23 hdp23 kerberos-env kdc_type mit-kdc

", there is some error:

USERID=admin

PASSWORD=admin

[ERROR] "kerberos-env" not found in server response.

Re: Kerberos configs page Can't open

What do you get as output if you do:

/var/lib/ambari-server/resources/scripts/configs.sh -u AMBARI_USER -p AMBARI_PASS get AMBARI_SERVER CLUSTER_NAME kerberos-env

Re: Kerberos configs page Can't open

OK, you are in a bad way. Can you get to Admin - Kerberos, and tell me do you have a disable kerberos button? I think your best bet would be to disable it, and then redeploy it.

Hi

It also failed in "Unkerberize Cluster" step, when I try to disable kerberos。Maybe there is some inconsistency in database。

There is the error log in ambari-server:
