示例1: map

import com.hazelcast.mapreduce.Context; //导入依赖的package包/类
@Override
public void map(String key, Person value, Context<String, Integer> context) {
    if (state != null) {
        if (!state.equals(value.getState())) {
            return;
        }
    }

    String name = abbrevationMapping.get(value.getState());

    IMap<String, SalaryYear> salariesMap = hazelcastInstance.getMap("salaries");

    // Person's partition key is email!
