Should we also delete Kafka topics before deleting the service? Will the topics still remain after deleting the service?

Hi @jsensharma , Is there any rest API call available for this recovery host option. That will be very helpful. Thanks, Bhuban

While starting Hortonworks sandbox it gets stuck on "extracting and loading the hortonworks sandbox..." And after some times it shows the message of critical error or sometimes it says "your system has ran into an error we'll restart it"

Move ats-hbase from the default queue to the yarn-system queue. yarn application -changeQueue yarn-system -appId <app-id> Here, <app-id> is the ID of the ats-hbase service. I stopped at this step and the alert notification still showing although I have restart the yarn and refresh yarn capacity scheduler, how I can find the app-id? I have try " yarn app -status ats-hbase " but it returns 20/07/30 01:42:49 INFO client.RMProxy: Connecting to ResourceManager at hdpdev02.bps.go.id/10.0.45.112:8050 20/07/30 01:42:49 INFO client.AHSProxy: Connecting to Application History server at hdpdev02.bps.go.id/10.0.45.112:10200 20/07/30 01:42:50 INFO client.RMProxy: Connecting to ResourceManager at hdpdev02.bps.go.id/10.0.45.112:8050 20/07/30 01:42:50 INFO client.AHSProxy: Connecting to Application History server at hdpdev02.bps.go.id/10.0.45.112:10200 ats-hbase Failed : HTTP error code : 500 NB: The cluster is a kerberized cluster

@Bender , Thank you. This helped is resolving the error.

dewi · ‎07-22-2020

YES! This solved my problem, it seems to be a bug in hiveserver mentioned in Apache bug reports. hive.metastore.event.db.notification.api.auth=false

fpaezalban · ‎07-10-2020

Thank you very much for this!!!!, It solves the problem registering host using ambari 2.7.3 and hdp 3.1.4 awesome!

hi @Jay SenSharma, thanks bro for sharing this info ,i had been stuck here completely for some days , now this will helpful, thanks again

The simple answer is: HDP is no longer free. this is the common pattern where a product is marketed as open source during the period the owner of the product gather data and improve the product. once mastered the product becomes commercial. I've learned that there is nothing free in this world.

jakezhang · ‎07-01-2020

Hi all, I had faced the same issue while kerberizing a HDP 3.1.0 cluster integrated with Iislon. The Ambari serer is a built on a Postgres DB cluster, hence it was NOT in the hadoop cluster. so it was NOT on the host list. [root@hdpdb ~]# curl -H "X-Requested-By: ambari" -u admin:admin "http://hdpdb.gz.local:8080/api/v1/clusters/Panyu/hosts" I had to add the ambari server from adding host wizard and just install the clients. It worked around the "Host not found, hostname= xxxx" issue in my case. Hope it will help, cheer!

It is likely the notebook definition than an interpreters.json Try out this solution, this is what helped me https://community.cloudera.com/t5/Support-Questions/Zeppelin-UI-returns-503-error-everytime/m-p/298374#M219128

Brother,you are a lifesaver

I'm getting the same issue. As you said, I think it might be coming from Nginx server.

Hi, Can you please have look at this: HBase 2nd Incremental Backup/Restore not Working

Karan1211 · ‎05-27-2020

I've followed all the steps, but I'm not getting these last steps. And, it's showing the same error. Please help me through it.

I faced similar issue, but REST api thru - http://localhost:8080/api/v1/cluster/[cluster_name]/services/KERBEROS was not available, and kerberos remove was giving error - "The 'krb5-conf' configuration is not available" in ambari-server.log We had Ambari 2.7.5.0. In that version clusterconfigmapping is not present, we had to do below procedure: In ambari db - psql -U ambari -d ambari (default password: bigdata) ambari=> select config_id, selected, create_timestamp from clusterconfig where type_name in ('kerberos-env', 'krb5-conf'); config_id | selected | create_timestamp -----------+----------+------------------ 352 | 0 | 1589796215822 452 | 0 | 1589800820822 << Select the record with latest timestamp 353 | 0 | 1589796215857 453 | 0 | 1589800820858 <<Select the record with latest timestamp (4 rows) ambari=> update clusterconfig set selected=1 where config_id=452; UPDATE 1 ambari=> update clusterconfig set selected=1 where config_id=453; UPDATE 1 ambari=> update clusterconfig set selected=1 where config_id=452; update clusterconfig set selected=1 where config_id=453; * Still the kerberos REST api was not been shown. * Remove the kerberos * Add kerberos back

@ansharma1 You can run the following query in Ambari DB SELECT view_instance_id,resource_id,view_name, cluster_handle,cluster_type FROM viewinstance; Above query will show that the view which is causing the problem might not be associated with any cluster_handle. (cluster_handle is basically the cluster_id, which you can see in the clusters table). If cluster_handle for a view is not correctly updated then you might see that kind of message: org.apache.ambari.server.view.IllegalClusterException: Failed to get cluster information associated with this view instance If you want to use the same old View to work fine (instead of creating a new Instance of that view) then you might have to make sure to update the cluster_handle for that view instance is set correctly. Like 1. Take ambari DB dump (latest dump for backup), As we are going to change the DB manually. 2. Stop ambari-server 3. Run the following queries in the amabri DB. NOTE: Following is just a dummy query the values for 'cluster_handle' and 'view_instance_id' in that query may vary. UPDATE viewinstance SET cluster_handle = 4 WHERE view_instance_id=3;

Hi @abhagi, Thanks for confirming this and great to know the issue got resolved! Please mark this thread as resolved when you get a chance. Cheers, Li

Hi Victor, did you find the solution. We are also into the same scenario and unable to install kerberos on HDP 3.1 though same steps worked smoothly on HDP 2.6. Kindly suggest if any recommendations.

OmThakare · ‎04-29-2020
