How do you Remove a Service from HDP via Ambari

awatson — Wed, 30 Sep 2015 20:20:33 GMT

I no longer have a use for Accumulo on my cluster and would like to delete the service. But when I tried to do that in Ambari, I noticed I could only add a service, not remove one.

You can do this with the Ambari REST API like so

curl -u $USER:$PASS -i -H 'X-Requested-By: ambari' -X DELETE  http://$AMBARI_HOST:$AMBARI_PORT/api/v1/clusters/<cluster-name>/services/<service-name>;

Andrew, you need to use the Ambari API for doing so. You will need to first clear all the nodes which do have a component and then you will need to uninstall the service. The documentation on how to do it can be found on the ambari wiki.

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

Here is an example removing METRICS_COLLECTOR from a host.

curl -u admin -H "X-Requested-By: ambari" -X DELETE http://localhost:8080/api/v1/clusters/POCHDPPM01/hosts/hdmdup0002.machine.test.group/host_components/METRICS_COLLECTOR

Unfortunately, does not seem to work with a failed install resulting in :

{ "status": 500, "message": "Server Error" }

you probably have residual components that need to be removed as well or put service state in stopped state. @Rick Barthelmie

I removed the residual components using the technique here:

And then the service deleted OK.

Remove the entry for service_name='Accumulo' from following five tables of ambari database in same sequence.

hostcomponentstate
hostcomponentdesiredstate
servicecomponentdesiredstate
