1.在本地跑集群的序列化测试时，报错

[INFO]

2.原因缺少jar包

解决方法：导入hadoop-mapreduce-client-common包

使用maven添加依赖

        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-mapreduce-client-common</artifactId>
            <version>3.1.3</version>
            <scope>compile</scope>
        </dependency>
