这段日志是一个Sqoop工具导出数据时发生的错误信息。其中，导出作业“job_1686300831839_0056”失败，原因是其中一个任务“task_1686300831839_0056_m_000001”执行失败。在计数器方面，总共有9个计数器被记录，其中有1个map任务失败，3个map任务被杀死，4个map任务被启动，所有的map任务都在本地数据块上执行，总共的map任务耗时20秒，共消耗了20374个vcore毫秒和20862976个MB毫秒的资源。此外，还有两个计数器组被警告信息所提醒，分别是“FileSystemCounters”和“org.apache.hadoop.mapred.Task$Counter”，它们都已经被弃用，建议使用“org.apache.hadoop.mapreduce.FileSystemCounter”和“org.apache.hadoop.mapreduce.TaskCounter”代替。在导出数据时，共传输了0字节的数据，在19.75秒内完成，导出了0条记录。最后，导出作业失败，导致导出工具“ExportTool”抛出了异常。
