flink中将数据赞一赞再执行countWindow函数

flink中将数据赞一赞再执行
数据分好组了(KeyBy),是组内计数,我们直接countWindow(5)即可
数据未未分组所以全局计数.countWindowAll(5)
例如
数据分好组的代码:

public class KeyBycountWindows {
    public static void main(String[] args) throws Exception {

        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

        DataStreamSource<String> lines = env.socketTextStream("localhost", 8888);

        //如果是划分窗口，如果调用keyBy分组（Keyed Stream），调用window

        SingleOutputStreamOperator<Tuple2<String, Integer>> wordAndOne = lines.map(new MapFunction<String, Tuple2<String, Integer>>() {
            @Override
            public Tuple2<String, Integer> map(String value) throws Exception {
                return Tuple2.of(value, 1);
            }
        });
        KeyedStream<Tuple2<String, Integer>, Tuple> keyedStream = wordAndOne.keyBy(1);

        //传入窗口分配器（划分器），传入具体划分窗口规则
        //CountWindw：按照条数划分窗口
        WindowedStream<Tuple2<String, Integer>, Tuple, GlobalWindow> noall = keyedStream.countWindow(5);
        SingleOutputStreamOperator<Tuple2<String, Integer>> summed = noall.sum(1);

        summed.print();

        env.execute();
    }
}

在端口依次输入:
hive
hive
hive
hive
hive

代码实现:
log4j:WARN No appenders could be found for logger (org.apache.flink.api.java.ClosureCleaner).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
3> (hive,5)

数据没有分好组的代码:

public class countWindowsAll {
    public static void main(String[] args) throws Exception {

        StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

        DataStreamSource<String> lines = env.socketTextStream("localhost", 8888);

        //如果是划分窗口，如果没有调用keyBy分组（Non-Keyed Stream），调用windowAll
        SingleOutputStreamOperator<Integer> nums = lines.map(Integer::parseInt);

        //传入窗口分配器（划分器），传入具体划分窗口规则
        //CountWindw：按照条数划分窗口
        AllWindowedStream<Integer, GlobalWindow> window = nums.countWindowAll(5);

        SingleOutputStreamOperator<Integer> result = window.sum(0);

        result.print();

        env.execute();
    }
}
在端口依次输入
