@Jay , this is what we got: ( so this is like 88% used ) , and regarding my question , how it can be 88% when disk are ~50% ... View more

@Jay, as you know we run the API that restart all req services, and what we mean is that we want to capture only the last status from restart action , ( so the req ID should be only the last ) , for example , if now the last req id is 187 , then on the next restart it will be 188 , so we want to capture only the status of req id - 188 ( fail / ok ) but as I mentioned my syntax is give this curl -sH "X-Requested-By: ambari" -u admin:admin -i http://$SERVER:8080/api/v1/clusters/$cluster_name/requests?fields=Requests/request_status | awk '/request_status/' | tail -1 | egrep -iq "FAILED|ABORTED" [[ $? -eq 0 ]] && echo fail || echo ok ...

@Jay see also what are the real latest restart status "href" : "http://master:8080/api/v1/clusters/HDP/requests/186", "Requests" : { "cluster_name" : "HDP", "id" : 186, "request_context" : "Restart all components for ZooKeeper", "request_status" : "ABORTED" } }, { "href" : "http://master:8080/api/v1/clusters/HDP/requests/187", "Requests" : { "cluster_name" : "HDP", "id" : 187, "request_context" : "Restart all components for Kafka", "request_status" : "COMPLETED" } }, { "href" : "http://master:8080/api/v1/clusters/HDP/requests/188", "Requests" : { "cluster_name" : "HDP", "id" : 188, "request_context" : "Restart all components for Kafka", "request_status" : "COMPLETED" } } ] ...

@Jay in my case we get the following and the expected results should be only the last line ( last restart results ) curl -sH "X-Requested-By: ambari" -u admin:admin -X GET http://$server:8080/api/v1/clusters/$cluster/requests?fields=Requests/id,Requests/request_status,Requests/request_context | grep -A2 -B3 "Restart all required services" | grep 'request_status' "request_status" : "COMPLETED" "request_status" : "COMPLETED" "request_status" : "COMPLETED" "request_status" : "FAILED" "request_status" : "COMPLETED" ...

@Jay I think the following syntax is more fit for my case curl -sH "X-Requested-By: ambari" -u admin:admin -i http://$SERVER:8080/api/v1/clusters/$cluster_name/requests?fields=Requests/request_status | awk '/request_status/' | tail -1 | egrep -iq "FAILED|ABORTED" it will capture the last status , and if this fail or abort then the status is fail what you think? ...
