我正在使用Sqoop将数据从oracle导入HDFS。当Job开始时，它会在5％的进度中停留大约1小时，这个信息是输出：
INFO mapreduce.Job: Task Id : attempt_1535519556038_0015_m_000037_0, Status : FAILED

然后继续，直到作业成功终止并导入所有数据。所以，我的问题是，在5％的进度中挂掉工作的原因是什么？为什么要自我纠正？这是正常的吗？如果没有，是否可以与发布的信息相关？我该如何解决这个问题？
错误消息清楚地解释了“未经授权的启动容器的请求。此令牌已过期“。
其中一个选项是通过设置来增加容器的使用寿命：yarn.resourcemanager.rm.container-allocation.expiry-interval-ms默认为10分钟。
注意：如果在yarn.resourcemanager.rm.container-allocation.expiry-interval-ms配置文件中增加yarn-site.xml，则作业将起作用。
