Example 1 with ReservedSlots

use of org.apache.flink.runtime.scheduler.adaptive.allocator.ReservedSlots in project flink by apache.

the class AdaptiveScheduler method tryToAssignSlots.

@Override
public CreatingExecutionGraph.AssignmentResult tryToAssignSlots(CreatingExecutionGraph.ExecutionGraphWithVertexParallelism executionGraphWithVertexParallelism) {
    final ExecutionGraph executionGraph = executionGraphWithVertexParallelism.getExecutionGraph();
    executionGraph.start(componentMainThreadExecutor);
    executionGraph.transitionToRunning();
    executionGraph.setInternalTaskFailuresListener(new UpdateSchedulerNgOnInternalFailuresListener(this));
    final VertexParallelism vertexParallelism = executionGraphWithVertexParallelism.getVertexParallelism();
    return slotAllocator.tryReserveResources(vertexParallelism).map(reservedSlots -> CreatingExecutionGraph.AssignmentResult.success(assignSlotsToExecutionGraph(executionGraph, reservedSlots))).orElseGet(CreatingExecutionGraph.AssignmentResult::notPossible);
}
