如何确定更改配置后重启哪些服务？
我需要使用Ambari API对我的集群进行一些更改。进行更改后，我将使用以下代码重新启动所有服务：
echo "stop and Start Services"
curl -k -v --user $AMBARI_USER:$AMBARI_PASSWORD -H "X-Requested-By: ambari" -i -X PUT -d '{"RequestInfo": {"context": "Stop All Services via REST"}, "ServiceInfo": {"state":"INSTALLED"}}' https://$AMBARI_HOST:$AMBARI_PORT/api/v1/clusters/$CLUSTER_NAME/services
sleep 200
curl -k -v --user $AMBARI_USER:$AMBARI_PASSWORD -H "X-Requested-By: ambari" -i -X PUT -d '{"RequestInfo": {"context": "Start All Services via REST"}, "ServiceInfo":{"state":"STARTED"}}' https://$AMBARI_HOST:$AMBARI_PORT/api/v1/clusters/$CLUSTER_NAME/services
sleep 700
这似乎是非常重要的。有没有办法只重启需要重启的服务？

一种选择是使用此选项仅重新启动因重新配置而需要重新启动的服务：
curl -v --user $AMBARI_USER:$AMBARI_PASSWORD -H "X-Requested-By: ambari" -i -X POST -d '{ "RequestInfo": {"command": "RESTART","context": "Restart all required services","operation_level": "host_component"}, "Requests/resource_filters": [{"hosts_predicate": "HostRoles/stale_configs=true" }] }' https://$AMBARI_HOST:$AMBARI_PORT/api/v1/clusters/$CLUSTER_NAME/requests
要检查上述命令的状态，请执行以下操作：
curl -v --user $AMBARI_USER:$AMBARI_PASSWORD -H "X-Requested-By: ambari" -X GET https://$AMBARI_HOST:$AMBARI_PORT/api/v1/clusters/$CLUSTER_NAME/requests/132
