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

@Ajay Kuppachi In case, if you are not able to delete the service using api then you need to check the service state in ambari database. Below are commands for same -

# psql -U ambari <= [password will be - bigdata, unless you have customize it.] ambari=>select * from servicedesiredstate where service_name='<service-name>' eg. ambari=>select * from servicedesiredstate where service_name='KNOX'

ambari=>select * from servicecomponentdesiredstate where service_name='<service-name>';

ambari=>select * from hostcomponentstate where service_name='<service-name>';

ambari=>select * from hostcomponentdesiredstate where service_name='<service-name>';

ambari=>quit;

You need to update the state accordingly.

Thanks

What is the cluster name you gave to your cluster? Replace c1 with that name.

My bad i replaced with clustername

{ "status" : 404, "message" : "The requested resource doesn't exist: Service not found, clusterName=HDP_QA, serviceName=Flume"

Service names are in upper case, do query with this first curl -u admin:admin -H "X-Requested-By: ambari" -X GET http://localhost:8080/api/v1/clusters/c1/services/

Make a note of all services you have, then do a get on individual services, replace cluster name in my query

@Ajay Kuppachi

You need to use something like the below one .

curl -u admin:admin -H "X-Requested-By: ambari" -X GET http://localhost:8080/api/v1/clusters/HDP_QA/services//FLUME_HANDLER

curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://localhost:8080/api/v1/clusters/HDP_QA/services/FALCON_SERVER

here are the list of components names Ambari understands,

[ { "name" : "KAFKA_BROKER" }, { "name" : "SUPERVISOR" }, { "name" : "METRICS_MONITOR" }, { "name" : "FLUME_HANDLER" }, { "name" : "SQOOP" }, { "name" : "YARN_CLIENT" }, { "name" : "FALCON_CLIENT" }, { "name" : "HDFS_CLIENT" }, { "name" : "OOZIE_CLIENT" }, { "name" : "YARN_CLIENT" }, { "name" : "ZOOKEEPER_CLIENT" }, { "name" : "HIVE_CLIENT" }, { "name" : "HCAT" }, { "name" : "MAPREDUCE2_CLIENT" }, { "name" : "HBASE_CLIENT" } ],

{ "name" : "NODEMANAGER" }, { "name" : "METRICS_MONITOR" }, { "name" : "DATANODE" }, { "name" : "SUPERVISOR" }, { "name" : "HBASE_REGIONSERVER"

{ "name" : "HBASE_MASTER" }, { "name" : "METRICS_MONITOR" }, { "name" : "ZOOKEEPER_SERVER" }, { "name" : "STORM_UI_SERVER" }, { "name" : "DRPC_SERVER" }, { "name" : "NIMBUS" }, { "name" : "WEBHCAT_SERVER" }, { "name" : "HIVE_SERVER" }, { "name" : "HIVE_METASTORE" }, { "name" : "TEZ_CLIENT" }, { "name" : "HCAT" }

{ "name" : "METRICS_MONITOR" }, { "name" : "METRICS_COLLECTOR" }, { "name" : "ZOOKEEPER_SERVER" }, { "name" : "HISTORYSERVER" }, { "name" : "APP_TIMELINE_SERVER" }, { "name" : "RESOURCEMANAGER" }, { "name" : "SECONDARY_NAMENODE" } { "name" : "NAMENODE" }, { "name" : "METRICS_MONITOR" }, { "name" : "ZOOKEEPER_SERVER" }
