how to print the hosts and IP address for each host By API

mike_bronson7 — Mon, 28 Aug 2017 12:09:08 GMT

the following API give only the hosts from the amabri server

curl -sH "X-Requested-By: ambari" -u admin:admin -i http://localhost:8080/api/v1/hosts

is it possible to change the API in way that we can get also the IP address for each host?

the following example print only the hosts :

curl -sH "X-Requested-By: ambari" -u admin:admin -i http://localhost:8080/api/v1/hosts | grep host_name | sed s'/"//g' | awk '{print $NF}'

master01

master02

master03

worker01

worker02

expected results

master01 192.9.200.12

master02 192.9.200.13

master03 192.9.200.14

worker01 192.9.200.15

worker02 192.9.200.16

You can try something like following:

# curl -sH "X-Requested-By: ambari" -u admin:admin -i http://localhost:8080/api/v1/hosts?fields=Hosts/host_name,Hosts/ip | grep -A 1 host_name | sed s'/"//g' | awk '{print $NF}'

Example Output:

# curl -sH "X-Requested-By: ambari" -u admin:admin -i http://amb25101.example.com:8080/api/v1/hosts?fields=Hosts/host_name,Hosts/ip | grep -A 1 host_name | sed s'/"//g' | awk '{print $NF}'
