Example 8 with ConflictException

use of co.cask.cdap.common.ConflictException in project cdap by caskdata.

the class ProgramLifecycleHttpHandler method startPrograms.

/**
   * Starts all programs 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
   * (flow name, service name, etc.). In additional, each object can contain an optional runtimeargs element,
   * which is a map of arguments to start the program with.
   * <p>
   * Example input:
   * <pre><code>
   * [{"appId": "App1", "programType": "Service", "programId": "Service1"},
   * {"appId": "App1", "programType": "Mapreduce", "programId": "MapReduce2", "runtimeargs":{"arg1":"val1"}},
   * {"appId": "App2", "programType": "Flow", "programId": "Flow1"}]
   * </code></pre>
   * </p><p>
   * The response will be an array of JsonObjects each of which will contain the three input parameters
   * as well as a "statusCode" field 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, App2 does not exist), then all JsonObjects for which the
   * parameters have a valid status will have the status 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 App2 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},
   * {"appId": "App1", "programType": "Mapreduce", "programId": "Mapreduce2", "statusCode": 200},
   * {"appId":"App2", "programType":"Flow", "programId":"Flow1", "statusCode":404, "error": "App: App2 not found"}]
   * </code></pre>
