Examples of KeysAssignmentOperation

com.hazelcast.mapreduce.impl.operation.KeysAssignmentOperation
This operation is used to request assignment for keys on the job owners node. The job owner is the only node capable of assigning those reducing nodes to be aware of the number of reducers per partition and also aware of possible topology changes while executing the job.

Examples of com.hazelcast.mapreduce.impl.operation.KeysAssignmentOperation

        try {
            MapReduceService mapReduceService = supervisor.getMapReduceService();
            String name = supervisor.getConfiguration().getName();
            String jobId = supervisor.getConfiguration().getJobId();
            KeysAssignmentResult assignmentResult = mapReduceService
                    .processRequest(supervisor.getJobOwner(), new KeysAssignmentOperation(name, jobId, keys), name);


            if (assignmentResult.getResultState() == SUCCESSFUL) {
                Map<Object, Address> assignment = assignmentResult.getAssignment();
                for (Map.Entry<Object, Address> entry : assignment.entrySet()) {
                    // Cache the keys for later mappings
