Falcon/Storm/Flume not Installed Properly as i am not able to Start/Stop Services .

[#1]

How can i delete these services and install again?

[#2]

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

[#3]

I get below Error when i run GET

# curl -u admin:admin -H "X-Requested-By: ambari" -X GET http://localhost:8080/api/v1/clusters/c1/services/FALCON { "status" : 404, "message" : "Parent Cluster resource doesn't exist. Cluster not found, clusterName=c1. Cluster not found, clusterName=c1"

[#4]

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

[#5]

My bad i replaced with clustername

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

[#6]

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 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.

@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"
