通过API进行Ambari群集+服务自动启动配置

Question

Ambari services can be configured to start automatically on system boot. Each service can be configured to start all components, masters and workers, or selectively.

so how to enable all services in ambari cluster to start automatically on system boot by API ?

Remark - by default all services are disabled

Answer 1

You may use auto-restart API, refer following document https://cwiki.apache.org/confluence/display/AMBARI/Recovery%3A+auto+start+components

Syntax. Following is syntax of API

curl -u admin:<password> -H "X-Requested-By: ambari" -X PUT 'http://<ambari host>:<ambari port>/api/v1/clusters/<cluster_name>/components?ServiceComponentInfo/component_name.in(<component name>)' -d '{"ServiceComponentInfo" : {"recovery_enabled":"true"}}'

Example . To set auto-restart for app timeline server component of YARN service use curl command as follows.

curl -u admin:<password> -H "X-Requested-By: ambari" -X PUT 'http://localhost:8080/api/v1/clusters/HDPCL/components?ServiceComponentInfo/component_name.in(APP_TIMELINE_SERVER)' -d '{"ServiceComponentInfo" : {"recovery_enabled":"true"}}'

NOTE : You can find list of components from http://<ambarihost>:<ambari port>/api/v1/clusters/Fenton/components
