How to clear / remove the failed host components / services after failed installation

muthukumar_siva — Fri, 05 Aug 2016 10:54:12 GMT

I tried installing the services HIVE, TEZ, PIG to the existing cluster and it got failed. I wanted to remove / clean up the components and services. In the Since the installation is failed, i could not find the component to decommission and then remove. Only HCAT got installed. Tried through API to remove the service, it is getting failed with the below error.

CSRF option is not in ambari.properties file as well.

$ cat /etc/ambari-server/conf/ambari.properties | grep -i CSR [root@ip-172-27-3-42.ap-southeast-1.compute.internal]:/home/ambari $

Hi can you try this command:

curl -u admin:admin -i -H 'X-Requested-By: ambari' -X DELETE http://AMBAIRHOST:8080/api/v1/clusters/CLUSTERNAME/services/HIVE

@Muthukumar S : The issue is with the double quotes you used around X-Requested-By: ambari. When I tried copy pasting the url you have pasted, I got the same issue as you.

I tried with single quotes like :

curl -u admin:admin -H 'X-Requested-By: ambari' -X DELETE -d ‘{“RequestInfo”:{“state”:”INSTALL_FAILED”}}’ http://172.22.127.69:8080/api/v1/clusters/cl1/services/HIVE

and it worked.

Have you used an editor which does a formatting because it looks like the quotes you used were special quotes which lead to the header not being read by curl.

Here is a link on how to delete a service. You will not be able to delete the service if it has components installed. The link has commands to delete components as well :

https://cwiki.apache.org/confluence/display/AMBARI/Using+APIs+to+delete+a+service+or+all+host+components+on+a+host

PS : Make sure when you copy/paste, you replace the double quotes in the terminal or a reliable editor.
