Any command to get active namenode for nameservice in hadoop?

Question

The command:

hdfs haadmin -getServiceState machine-98

Works only if you know the machine name. Is there any command like:

h         


        

Answer 1

You can do a curl command to find out the Active and secondary Namenode for example

curl -u username -H "X-Requested-By: ambari" -X GET http://cluster-hostname:8080/api/v1/clusters//services/HDFS
