Hive-clients with Curl command

reddyr211 — Thu, 08 Mar 2018 07:21:05 GMT

Hello HCC,

We have a production cluster with 800+ data nodes and hive-clients installed one more than 200+ nodes, i can see that from Ambari

is there a simple way or CURL command to find all hive-clients installed in the cluster which i can see on Cli/Linux box.

HDP:2.6.1

Ambari 2.5.2.0

Thanks,Jalender.

@Jalender

Here is an example for YARN_CLIENT

// Getting the state of the component

curl -k -u admin:admin -H "X-Requested-By:ambari" -i -X GET
http://<HOST>:8080/api/v1/clusters/<CLUSTER_NAME>/hosts/<HOST_FQDN>/host_components/YARN_CLIENT

Hope that helps

@Jalender,

You can use this command to print all the hosts on which HIVE_CLIENT is installed

curl -k -u {ambari-username}:{ambari-password} -H "X-Requested-By:ambari" http://{ambari-host}:{ambari-port}/api/v1/clusters/{cluster-name}/services/HIVE/components/HIVE_CLIENT | grep host_name | awk '{ print $3 }'

Replace all the placeholders before running.
