Example 33 with BadRequestException

use of io.cdap.cdap.common.BadRequestException in project cdap by caskdata.

the class ProgramLifecycleHttpHandler method getRunCounts.

/**
 * Returns the run counts for all program runnables that are passed into the data. The data is an array of
 * Json objects where each object must contain the following three elements: appId, programType, and programId.
 * The max number of programs in the request is 100.
 * <p>
 * Example input:
 * <pre><code>
 * [{"appId": "App1", "programType": "Service", "programId": "Service1"},
 *  {"appId": "App1", "programType": "Workflow", "programId": "testWorkflow"},
 *  {"appId": "App2", "programType": "Workflow", "programId": "DataPipelineWorkflow"}]
 * </code></pre>
 * </p><p>
 * </p><p>
 * The response will be an array of JsonObjects each of which will contain the three input parameters
 * as well as 2 fields, "runCount" which maps to the count of the program and "statusCode" which maps to the
 * status code for the data in that JsonObjects.
 * </p><p>
 * If an error occurs in the input (for the example above, workflow in app1 does not exist),
 * then all JsonObjects for which the parameters have a valid status will have the count field but all JsonObjects
 * for which the parameters do not have a valid status will have an error message and statusCode.
 * </p><p>
 * For example, if there is no workflow in App1 in the data above, then the response would be 200 OK with following
 * possible data:
 * </p>
 * <pre><code>
 * [{"appId": "App1", "programType": "Service", "programId": "Service1",
 * "statusCode": 200, "runCount": 20},
 * {"appId": "App1", "programType": "Workflow", "programId": "testWorkflow", "statusCode": 404,

 *  {"appId": "App2", "programType": "Workflow", "programId": "DataPipelineWorkflow",
 *  "statusCode": 200, "runCount": 300}]
 * </code></pre>
