My original goal is move the component to another node. So I just did as Panwar said in https://community.hortonworks.com/questions/4272/process-for-moving-hdp-services-manually.html.I did not call API in order like Panwar tips: SPARK>:8080/api/v1/clusters/clustername/services/SPARK
curl -u admin:admin -H "X-Requested-By: ambari" -X PUT -d '{"RequestInfo":{"context":"Stop Component"},"Body":{"HostRoles":{"state":"INSTALLED"}}}' http://:8080/api/v1/clusters/clustername/services/SPARK>:8080/api/v1/clusters/clustername/hosts/<old-host>/host_components/SPARK_JOBHISTORYSERVER
curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://:8080/api/v1/clusters/clustername/services/SPARK>:8080/api/v1/clusters/clustername/services/SPARK/components/SPARK_JOBHISTORYSERVER I delete the component when it's still running: curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://namenode01.will.com:8080/api/v1/clusters/datacenter/services/SPARK/components/SPARK_JOBHISTORYSERVER
then, the component disappeared from the stack. I cannot find it from http://namenode01.will.com:8080/api/v1/clusters/datacenter/services/SPARK/components now: {
"href" : "http://namenode01.will.com:8080/api/v1/clusters/datacenter/services/SPARK/components",
"items" : [
{
"href" : "http://namenode01.will.com:8080/api/v1/clusters/datacenter/services/SPARK/components/SPARK_CLIENT",
"ServiceComponentInfo" : {
"cluster_name" : "datacenter",
"component_name" : "SPARK_CLIENT",
"service_name" : "SPARK"
}
},
{
"href" : "http://namenode01.will.com:8080/api/v1/clusters/datacenter/services/SPARK/components/SPARK_THRIFTSERVER",
"ServiceComponentInfo" : {
"cluster_name" : "datacenter",
"component_name" : "SPARK_THRIFTSERVER",
"service_name" : "SPARK"
}
}
]
} It also disappeared from the UI. So, anybody help me, please?
