Subject: How to update config group of existing cluster and make it effective
using ambari REST API call?
Hi guys,
I have a problem when I updating config group using ambari REST API call.
Problem: The config group can’t update in existing cluster when I using ambari
REST API call.
Following is the REST API call details:
1. Info of config_group before updating it using REST API call:
{
"href" :
"https://wdc-vhadp-pub2-dhcp-72-204.eng.vmware.com:8443/api/v1/clusters/am_1/config_groups/19";,
"ConfigGroup" : {
"cluster_name" : "am_1",
"description" : "Host Group Configuration",
"desired_configs" : [
{
"tag" : "version1429860457538",
"type" : "hdfs-site",
"href" :
"https://wdc-vhadp-pub2-dhcp-72-204.eng.vmware.com:8443/api/v1/clusters/am_1/configurations?type=hdfs-site&tag=version1429860457538";
}
],

"hosts" : [
{
"host_name" : "wdc-vhadp-pub2-dhcp-72-158.eng.vmware.com",

}
],

"tag" : "HDFS"
}
}
{

"tag" : "version1429860457538",
"type" : "hdfs-site",
"version" : 9,
"Config" : {
"cluster_name" : "am_1"
},

}
}

}
}
]
}
The response of REST API call is 200 OK, but the config_group info is still old
one. Can you tell me How to update config group of existing cluster and make it
effective using ambari REST API call?
Thanks,
