Find the hostnames where the "SPARK2_THRIFTSERVER" server is running:

# curl -H "X-Requested-By: ambari" -u admin:admin -X GET "http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/hosts?(host_components/HostRoles/component_name=SPARK2_THRIFTSERVER)&minimal_response=true"  | grep host_name | awk -F":" '{print $2}' |  awk -F"\"" '{print $2}'


Example Output:
newhwx3.example.com
newhwx5.example.com


Once we know the hosts where the "SPARK2_THRIFTSERVER" is running then we can run the following command by replacing the host newhws3 and newhwx5 to turn ON the maintenance mode for it.

# curl -H "X-Requested-By: ambari" -u admin:admin -X PUT -d '{"RequestInfo":{"context":"Turn ON Maintenance Mode for Spark2 Thrift Server"},"Body":{"HostRoles":{"maintenance_state":"ON"}}}' "http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/hosts/newhwx3.example.com/host_components/SPARK2_THRIFTSERVER"

# curl -H "X-Requested-By: ambari" -u admin:admin -X PUT -d '{"RequestInfo":{"context":"Turn ON Maintenance Mode for Spark2 Thrift Server"},"Body":{"HostRoles":{"maintenance_state":"ON"}}}' "http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/hosts/newhwx5.example.com/host_components/SPARK2_THRIFTSERVER"


.


Turn OFF maintenance Mode for Spark2 thrift server on newhwx3 and newhws5

# curl -H "X-Requested-By: ambari" -u admin:admin -X PUT -d '{"RequestInfo":{"context":"Turn OFF Maintenance Mode for Spark2 Thrift Server"},"Body":{"HostRoles":{"maintenance_state":"OFF"}}}' "http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/hosts/newhwx3.example.com/host_components/SPARK2_THRIFTSERVER"

# curl -H "X-Requested-By: ambari" -u admin:admin -X PUT -d '{"RequestInfo":{"context":"Turn OFF Maintenance Mode for Spark2 Thrift Server"},"Body":{"HostRoles":{"maintenance_state":"OFF"}}}' "http://newhwx1.example.com:8080/api/v1/clusters/NewCluster/hosts/newhwx5.example.com/host_components/SPARK2_THRIFTSERVER"
