@kishore sanchina For example when you will access the API: http://erie1.example.com:8080/api/v1/clusters/ErieCluster/alert_definitions/33 Then you might get the following kind of output: {
href: "http://erie1.example.com:8080/api/v1/clusters/ErieCluster/alert_definitions/33",
AlertDefinition: {
cluster_name: "ErieCluster",
component_name: "APP_TIMELINE_SERVER",
description: "This host-level alert is triggered if the App Timeline Server Web UI is unreachable.",
enabled: true,
help_url: null,
id: 47,
ignore_host: false,
interval: 1,
label: "App Timeline Web UI",
name: "yarn_app_timeline_server_webui",
repeat_tolerance: 1,
repeat_tolerance_enabled: false,
scope: "ANY",
service_name: "YARN",
source: {
reporting: {
ok: {
text: "HTTP {0} response in {2:.3f}s"
},
warning: {
text: "HTTP {0} response from {1} in {2:.3f}s ({3})"
},
critical: {
text: "Connection failed to {1} ({3})"
}
},
type: "WEB",
uri: {
http: "{{yarn-site/yarn.timeline-service.webapp.address}}/ws/v1/timeline",
https: "{{yarn-site/yarn.timeline-service.webapp.https.address}}/ws/v1/timeline",
https_property: "{{yarn-site/yarn.http.policy}}",
https_property_value: "HTTPS_ONLY",
kerberos_keytab: "{{yarn-site/yarn.timeline-service.http-authentication.kerberos.keytab}}",
kerberos_principal: "{{yarn-site/yarn.timeline-service.http-authentication.kerberos.principal}}",
default_port: 0,
connection_timeout: 5
}
}
}
} - Then while putting the above edited JSON data back to ambari you should remove the second line from it ...which is following: href: "http://erie1.example.com:8080/api/v1/clusters/ErieCluster/alert_definitions/33" .
