Example 38 with BadRequestException

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

the class TimelineReaderWebServices method getFlowRuns.

/**
   * Return a list of flow runs for given UID which is a delimited string
   * containing clusterid, userid and flow name.
   *
   * @param req Servlet request.
   * @param res Servlet response.
   * @param uId a delimited string containing clusterid, userid, and flow name
   *     which are extracted from UID and then used to query backend(Mandatory
   *     path param).
   * @param limit If specified, defines the number of flow runs to return. The
   *     maximum possible value for limit can be {@link Long#MAX_VALUE}. If it
   *     is not specified or has a value less than 0, then limit will be
   *     considered as 100. (Optional query param).
   * @param createdTimeStart If specified, matched flow runs should not be
   *     created before this timestamp(Optional query param).
   * @param createdTimeEnd If specified, matched flow runs should not be created
   *     after this timestamp(Optional query param).
   * @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 to retrieve, see {@link Field}. All
   *     fields will be retrieved if fields=ALL. Amongst all the fields, only
   *     METRICS makes sense for flow runs hence only ALL or METRICS are
   *     supported as fields for fetching flow runs. Other fields will lead to
   *     HTTP 400 (Bad Request) response. (Optional query param).
   *
   * @return If successful, a HTTP 200(OK) response having a JSON representing a
   *     set of <cite>FlowRunEntity</cite> instances for the given flow are
   *     returned.<br>
   *     On failures,<br>
   *     If any problem occurs in parsing request or UID is incorrect,
   *     HTTP 400(Bad Request) is returned.<br>
   *     For all other errors while retrieving data, HTTP 500(Internal Server
   *     Error) is returned.
