Examples with ResourceReport org.apache.twill.api.ResourceReport used on opensource projects

Example 1 with ResourceReport

use of org.apache.twill.api.ResourceReport in project cdap by caskdata.

the class DistributedProgramRuntimeService method createController.

@Nullable
private ProgramController createController(ProgramDescriptor programDescriptor, TwillController controller, RunId runId) {
    ProgramId programId = programDescriptor.getProgramId();

    try {
        programRunner = programRunnerFactory.create(programId.getType());
    } catch (IllegalArgumentException e) {
        // This shouldn't happen. If it happen, it means CDAP was incorrectly install such that some of the program
        // type is not support (maybe due to version mismatch in upgrade).
        LOG.error("Unsupported program type {} for program {}. " + "It is likely caused by incorrect CDAP installation or upgrade to incompatible CDAP version", programId.getType(), programId);
        return null;
    }
    if (!(programRunner instanceof DistributedProgramRunner)) {
        // This is also unexpected. If it happen, it means the CDAP core or the runtime provider extension was wrongly
        // implemented
        ResourceReport resourceReport = controller.getResourceReport();
        LOG.error("Unable to create ProgramController for program {} for twill application {}. It is likely caused by " + "invalid CDAP program runtime extension.", programId, resourceReport == null ? "'unknown twill application'" : resourceReport.getApplicationId());
