how to enable service auto start by API as the following
Do you mean something similar to the one which is mentioned here:
the api from from this link answer about to enable all services , but what we need is only to enable / disable the auto start services , as described in the pictures ( like click on button to disable (pic1) ,and click on the button to enable (pic2) )
Through API call it will be bit complex because ambari client needs to send a very huge Payload to make that change.
However the easiest option will be to use the following approach from ambari server host:
To Enable Auto start Services
# /var/lib/ambari-server/resources/scripts/configs.py --user=admin --password=admin --port=8080 --action=set --host=localhost --cluster=TestCluster --config-type=cluster-env -k "recovery_enabled" -v "true"
To Disable Auto start Services
# /var/lib/ambari-server/resources/scripts/configs.py --user=admin --password=admin --port=8080 --action=set --host=localhost --cluster=TestCluster --config-type=cluster-env -k "recovery_enabled" -v "false"
Please change the Cluster name "TestCluster" and ambari credentials in the above script .
Above script needs to be executed from ambari server host as it has the "" file.
@Jay thank you so much , regrading the cluster size ( ) , dose cluster size mean - Number of workers machines ?
