Ambari API call to retrieve hostname of active HBase master?

rchoksi — Sat, 25 Mar 2017 05:55:59 GMT

Using Ambari apis, is there a way to get the host name of the Active HBase Master?

@Romil Choksi You can use additional queries in the GET HostComponents API

e.g

<AMBARI_HOST>/api/v1/clusters/cl1/host_components?HostRoles/component_name=HBASE_MASTER&metrics/hbase/master/IsActiveMaster=true	

Hope this helps!

You can prepare similar queries by identifying the fields defined using query parameter ?fields=* with most of the ambari APIs

e.g  <AMBARI_HOST>/api/v1/clusters/cl1/host_components?fields=*
