@Michael Bronson One solution can be as following: # export HOST=amb25101.example.com # export USER=admin # export PASSWD=admin # export ACTION=INSTALLED # export CLUSTER_NAME=plain_ambari # echo {"\"RequestInfo\": {\"context\" :\"Stop AMBARI_METRICS via REST\"}, \"Body\": {\"ServiceInfo\": {\"state\": \"$ACTION\"}}}" > /tmp/postData.txt # curl -u $USER:$PASSWD -i -H 'X-Requested-By: ambari' -X PUT -d@/tmp/postData.txt http://$HOST:8080/api/v1/clusters/$CLUSTER_NAME/services/AMBARI_METRICS . So basically we are doing the following thing differently: # echo {"\"RequestInfo\": {\"context\" :\"Stop AMBARI_METRICS via REST\"}, \"Body\": {\"ServiceInfo\": {\"state\": \"$ACTION\"}}}" > /tmp/postData.txt # curl -u $USER:$PASSWD -i -H 'X-Requested-By: ambari' -X PUT -d@/tmp/postData.txt http://$HOST:8080/api/v1/clusters/$CLUSTER_NAME/services/AMBARI_METRICS . ...

@Michael Bronson What you are seeing in the output of the API call is actually the HTTP Response which ambari has sent to the client. { "href": "http://localhost:8080/api/v1/clusters/sys15626/requests/128", "Requests": { "id": 128, "status": "Accepted" } } Above is a standard API response from ambari when a request is accepted. The only option to get only the ID part is to use the response parsing mechanism provided by OS like grep. (Or using Custom parsing utility / third party APIs) . Example: # cat /tmp/response.txt | grep id | awk '{print $NF}' | cut -d , -f1 ... View more

@Michael Bronson, You can use the below API curl -u {ambari-username}:{ambari-password} -H "X-Requested-By: ambari" -X PUT -d '{"RequestInfo":{"context":"_PARSE_.START.ALL_SERVICES","operation_level":{"level":"CLUSTER","cluster_name":"hdp"}},"Body":{"ServiceInfo":{"state":"STARTED"}}}' http://{ambari-host}:{ambari-port}/api/v1/clusters/{cluster-name}/services Replace ambari-username, ambari-password, ambari-host, ambari-port, cluster-name with respective values Note: Cluster Name should be replaced in 2 places. One in the url {cluster-name} and the other one in the json which I put as hdp Thanks, Aditya ... View more

@Michael Bronson, Safe mode above applies only for NameNode and not for any other services/components. The above command gives you the safe mode status of 2 nodes (Active NameNode and standby NameNode) You can read more about safe mode from the below links http://hadooptutorial.info/safe-mode-in-hadoop/ http://data-flair.training/forums/topic/what-is-safemode-in-hadoop Thanks, Aditya ...
