YarnApplicationsResourceApi

All URIs are relative to https://localhost/api/v40

Method HTTP request Description
getYarnApplicationAttributes GET /clusters/{clusterName}/services/{serviceName}/yarnApplications/attributes Returns the list of all attributes that the Service Monitor can associate with YARN applications.
getYarnApplications GET /clusters/{clusterName}/services/{serviceName}/yarnApplications Returns a list of applications that satisfy the filter.
killYarnApplication POST /clusters/{clusterName}/services/{serviceName}/yarnApplications/{applicationId}/kill Kills an YARN Application.

getYarnApplicationAttributes

ApiYarnApplicationAttributeList getYarnApplicationAttributes(clusterName, serviceName)

Returns the list of all attributes that the Service Monitor can associate with YARN applications.

Returns the list of all attributes that the Service Monitor can associate with YARN applications.

Examples of attributes include the user who ran the application and the number of maps completed by the application.

These attributes can be used to search for specific YARN applications through the getYarnApplications API. For example the 'user' attribute could be used in the search 'user = root'. If the attribute is numeric it can also be used as a metric in a tsquery (ie, 'select maps_completed from YARN_APPLICATIONS').

Note that this response is identical for all YARN services.

Available since API v6.

String clusterName = "clusterName_example"; // String | 
String serviceName = "serviceName_example"; // String | The name of the service
String filter = ""; // String | A filter to apply to the applications. A basic filter tests the value of an attribute and looks something like 'executing = true' or 'user = root'.

An example of a complex filter is: 'application_duration > 5s and (user = root or user = myUserName').
String from = "from_example"; // String | Start of the period to query in ISO 8601 format (defaults to 5 minutes before the 'to' time).
Integer limit = 100; // Integer | The maximum number of applications to return. Applications will be returned in the following order: <ul> <li> All executing applications, ordered from longest to shortest running </li> <li> All completed applications order by end time descending. </li> </ul>
Integer offset = 0; // Integer | The offset to start returning applications from. This is useful for paging through lists of applications. Note that this has non-deterministic behavior if executing applications are included in the response because they can disappear from the list while paging. To exclude executing applications from the response and a 'executing = false' clause to your filter.
String to = "now"; // String | End of the period to query in ISO 8601 format (defaults to now).
