看到这个错误我就网上一顿搜索并修改，但是都没有找到解决方案。
在我灰心意冷的时候看到了错误中关于sql的日志，如下：
No Stats for sonkwo@ods_event_log, Columns: ip_region, create_time, ip, source_parameter, v_uuid, account_region, visit_page_time, version, url, path, account_id, event_type, detail_parameter, account_register_time, page_name, host, page_parameter, client, goto_parameter, id, event_time 05-01-2022 10:21:01 CST ods_to_dwd_log INFO - No Stats for sonkwo@ods_event_log, Columns: account_id, v_uuid, id, event_time 05-01-2022 10:21:01 CST ods_to_dwd_log INFO - No Stats for sonkwo@ods_event_log, Columns: ip_region, create_time, ip, source_parameter, v_uuid, account_region, visit_page_time, version, url, path, account_id, event_type, detail_parameter, account_register_time, page_name, host, page_parameter, client, goto_parameter, id, event_time
我心想，为什么会有这个日志线上呢，是不是我使用了“select * from” ,因为对于hive来说最好把要查询的列都写出来，那我就改一下这个问题吧，省的看的心烦。
奇迹出现了，改完这个问题后，重新跑azkaban竟然跑成功了。
启发，日志有时候并不能很明确的爆出错误，但是要尽量去看去解决，也许一些小问题就是导致错误的根本原因！！！！
