Example 21 with NotFoundException

use of org.apache.hadoop.yarn.webapp.NotFoundException in project hadoop by apache.

the class TimelineReaderWebServices method getApp.

/**
   * Return a single app for given cluster id and app id. If userid, flow name
   * and flowrun id which are optional query parameters are not specified, they
   * will be queried based on app id and cluster id from the flow context
   * information stored in underlying storage implementation.
   *
   * @param req Servlet request.
   * @param res Servlet response.
   * @param clusterId Cluster id to which the app to be queried belong to(
   *     Mandatory path param).
   * @param appId Application id to be queried(Mandatory path param).
   * @param flowName Flow name which should match for the app(Optional query
   *     param).
   * @param flowRunId Run id which should match for the app(Optional query
   *     param).
   * @param userId User id which should match for the app(Optional query param).
   * @param confsToRetrieve If specified, defines which configurations to
   *     retrieve and send back in response. These configs will be retrieved
   *     irrespective of whether configs are specified in fields to retrieve or
   *     not.
   * @param metricsToRetrieve If specified, defines which metrics to retrieve
   *     and send back in response. These metrics will be retrieved
   *     irrespective of whether metrics are specified in fields to retrieve or
   *     not.
   * @param fields Specifies which fields of the app entity object to retrieve,
   *     see {@link Field}. All fields will be retrieved if fields=ALL. If not
   *     specified, 3 fields i.e. entity type(equivalent to YARN_APPLICATION),
   *     app id and app created time is returned(Optional query param).
   * @param metricsLimit If specified, defines the number of metrics to return.
   *     Considered only if fields contains METRICS/ALL or metricsToRetrieve is
   *     specified. Ignored otherwise. The maximum possible value for
   *     metricsLimit can be {@link Integer#MAX_VALUE}. If it is not specified
   *     or has a value less than 1, and metrics have to be retrieved, then
   *     metricsLimit will be considered as 1 i.e. latest single value of
   *     metric(s) will be returned. (Optional query param).
   *
   * @return If successful, a HTTP 200(OK) response having a JSON representing a
   *     <cite>TimelineEntity</cite> instance is returned.<br>
   *     On failures,<br>
   *     If any problem occurs in parsing request, HTTP 400(Bad Request) is
   *     returned.<br>
   *     If flow context information cannot be retrieved or app for the given
   *     app id cannot be found, HTTP 404(Not Found) is returned.<br>
   *     For all other errors while retrieving data, HTTP 500(Internal Server
   *     Error) is returned.
