Apache flink Apache Flink:网络缓冲区数量不足

我创建了一个flink quickstart java（DarchetypeArtifactId）项目。 下面是一个示例代码WordCount.java

这是原始WordCount.java代码的一部分

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

    // set up the execution environment
    final ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();

    // get input data
    DataSet<String> text = env.fromElements(
            "To be, or not to be,--that is the question:--",
            "Whether 'tis nobler in the mind to suffer",
            "The slings and arrows of outrageous fortune",
            "Or to take arms against a sea of troubles,"
            );
    //DataSet<String> text = env.readTextFile("file:///home/jypark2/data3.txt");

    DataSet<Tuple2<String, Integer>> counts =
            // split up the lines in pairs (2-tuples) containing: (word,1)
            text.flatMap(new LineSplitter())
            // group by the tuple field "0" and sum up tuple field "1"
            .groupBy(0)
            .sum(1);

    // execute and print result
    counts.print();

}

及

重新启动taskmanager、JobManager、， 本地，但错误消息相同。 页面localhost:8081上的配置已更改，但 错误消息的数量不会更改

此外，我还运行了示例代码SocketTextStreamWordCount.java 没有任何变化。但类似的错误也发生了，错误信息说 网络缓冲区数量不足：需要64个，但只需要36个 可用。网络缓冲区的总数当前设置为2048

我怎样才能解决这个问题？帮帮我

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

    // set up the execution environment
    final ExecutionEnvironment env = ExecutionEnvironment.getExecutionEnvironment();

    // get input data

    DataSet<String> text = env.readTextFile("file:///home/jypark2/data3.txt");

    DataSet<Tuple2<String, Integer>> counts =
            // split up the lines in pairs (2-tuples) containing: (word,1)
            text.flatMap(new LineSplitter())
            // group by the tuple field "0" and sum up tuple field "1"
            .groupBy(0)
            .sum(1);

    // execute and print result
    counts.print();

}
