Examples with IntermediateChunkNotification com.hazelcast.mapreduce.impl.notification.IntermediateChunkNotification used on opensource projects

Example 1 with IntermediateChunkNotification

use of com.hazelcast.mapreduce.impl.notification.IntermediateChunkNotification in project hazelcast by hazelcast.

the class JobSupervisor method onNotification.

public void onNotification(MapReduceNotification notification) {
    if (notification instanceof IntermediateChunkNotification) {
        IntermediateChunkNotification icn = (IntermediateChunkNotification) notification;
        ReducerTask reducerTask = jobTracker.getReducerTask(icn.getJobId());
        reducerTask.processChunk(icn.getChunk());
    } else if (notification instanceof LastChunkNotification) {
        LastChunkNotification lcn = (LastChunkNotification) notification;
        ReducerTask reducerTask = jobTracker.getReducerTask(lcn.getJobId());
        reducerTask.processChunk(lcn.getPartitionId(), lcn.getSender(), lcn.getChunk());
    } else if (notification instanceof ReducingFinishedNotification) {
        final ReducingFinishedNotification rfn = (ReducingFinishedNotification) notification;
        // Just offload it to free the event queue
        executorService.submit(new Runnable() {

            @Override
            public void run() {
                processReducerFinished0(rfn);
            }
        });
    }
}

Example 2 with IntermediateChunkNotification

use of com.hazelcast.mapreduce.impl.notification.IntermediateChunkNotification in project hazelcast by hazelcast.

the class MapCombineTask method onEmit.

void onEmit(DefaultContext<KeyOut, ValueOut> context, int partitionId) {
    // we need to collect all values locally and wait for final request
    if (supervisor.getConfiguration().getReducerFactory() != null) {
        if (context.getCollected() == chunkSize) {
            Map<KeyOut, Chunk> chunkMap = context.requestChunk();
            // Wrap into IntermediateChunkNotification object
            Map<Address, Map<KeyOut, Chunk>> mapping = mapResultToMember(supervisor, chunkMap);
            // Register remote addresses and partitionId for receiving reducer events
            supervisor.registerReducerEventInterests(partitionId, mapping.keySet());
            for (Map.Entry<Address, Map<KeyOut, Chunk>> entry : mapping.entrySet()) {
                mapReduceService.sendNotification(entry.getKey(), new IntermediateChunkNotification(entry.getKey(), name, jobId, entry.getValue(), partitionId));
            }
        }
    }
