Example 6 with ConflictException

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

the class DatasetAdminOpHTTPHandler method update.

@POST
@Path("/data/datasets/{name}/admin/update")
public void update(FullHttpRequest request, HttpResponder responder, @PathParam("namespace-id") String namespaceId, @PathParam("name") String name) throws Exception {
    propagateUserId(request);

    Preconditions.checkArgument(params.getTypeMeta() != null, "Missing required 'typeMeta' parameter.");
    Preconditions.checkArgument(params.getExistingSpec() != null, "Missing required 'existingSpec' parameter.");

Example 7 with ConflictException

use of io.cdap.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"}}]
 * </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": "App2", "programType": "Mapreduce", "programId": "Mapreduce2",
 *  "statusCode":404, "error": "App: App2 not found"}]
 * </code></pre>
