Examples with Operation com.hazelcast.spi.Operation used on opensource projects

Example 46 with Operation

use of com.hazelcast.spi.Operation in project hazelcast-jet by hazelcast.

the class MasterContext method invokeOnParticipants.

private void invokeOnParticipants(Map<MemberInfo, InternalCompletableFuture<Object>> futures, CompletableFuture<Void> doneFuture, Function<ExecutionPlan, Operation> opCtor) {
    AtomicInteger remainingCount = new AtomicInteger(executionPlanMap.size());
    for (Entry<MemberInfo, ExecutionPlan> e : executionPlanMap.entrySet()) {
        MemberInfo member = e.getKey();
        Operation op = opCtor.apply(e.getValue());
        InternalCompletableFuture<Object> future = nodeEngine.getOperationService().createInvocationBuilder(JetService.SERVICE_NAME, op, member.getAddress()).setDoneCallback(() -> {
            if (remainingCount.decrementAndGet() == 0) {
                doneFuture.complete(null);
            }
        }).invoke();
        futures.put(member, future);
    }
}

Example 47 with Operation

use of com.hazelcast.spi.Operation in project hazelcast-jet by hazelcast.

the class MasterContext method invokeStartExecution.

// If a participant leaves or the execution fails in a participant locally, executions are cancelled
// on the remaining participants and the callback is completed after all invocations return.
private void invokeStartExecution() {
    logger.fine("Executing " + jobIdString());
    long executionId = this.executionId;
    ExecutionInvocationCallback callback = new ExecutionInvocationCallback(executionId);

    CompletionToken executionRestartToken = new CompletionToken(logger);
    executionRestartToken.whenCompleted(callback::cancelInvocations);
    Function<ExecutionPlan, Operation> operationCtor = plan -> new StartExecutionOperation(jobId, executionId);
    Consumer<Map<MemberInfo, Object>> completionCallback = results -> {
        this.executionRestartToken = null;
        onExecuteStepCompleted(results, executionRestartToken.isCompleted());
    };
    // We must set executionRestartToken before we call invoke() method because once all invocations
    // are done, executionRestartToken will be reset. Therefore, setting it after the invoke() call is racy.
    this.executionRestartToken = executionRestartToken;
    jobStatus.set(RUNNING);
    invoke(operationCtor, completionCallback, callback);
    if (isSnapshottingEnabled()) {
        coordinationService.scheduleSnapshot(jobId, executionId);

Example 48 with Operation

use of com.hazelcast.spi.Operation in project hazelcast-jet by hazelcast.

the class JobExecutionService method initExecution.

/**
 * Initiates the given execution if the local node accepts the coordinator
 * as its master, and has an up-to-date member list information.
 * <ul><li>
 *   If the local node has a stale member list, it retries the init operation
 *   until it receives the new member list from the master.
 * </li><li>
 *     If the local node detects that the member list changed after the init
 *     operation is sent but before executed, then it sends a graceful failure
 *     so that the job init will be retried properly.
 * </li><li>
 *     If there is an already ongoing execution for the given job, then the
 *     init execution is retried.
 * </li></ul>
