how to find number of CPU core on datanode machine by ambari rest API

avatar

Hi all

 

 

I am running the following ambari API in order to find the CPU count on data node machine

 

 

curl -H "X-Requested-By: ambari" -u admin:admin -X GET http://master:8080/api/v1/clusters/hdp_test/hosts?fields=Hosts/host_name,Hosts/public_host_name,Host...

 

we get the error about:

 

 

{

  "status" : 400,

  "message" : "The properties [host_compnents/HostRoles/component_name] specified in the request or predicate are not supported for the resource type Host."

 

 

The target is to find the number of cpu on data node machine as we can do it on datanode linux machine

 

nproc
