查源表数据：
查询目标表数据:
排查过程：
1.通过sqoop eval查询数据正常Sqoop_query "select car_owner ,replace(car_owner,'|','') as car_owner0 from tpkhrew.rew_policy limit 2"-----------------------------------------------| car_owner | car_owner0 |-----------------------------------------------| B44ED76EE02EF56511A35A0431CAB867 | B44ED76EE02EF56511A35A0431CAB867 || 3909889A8B265DC98ACC98C3A1930A1F | 3909889A8B265DC98ACC98C3A1930A1F |-----------------------------------------------
2.落hdfs数据异常，
3.查源表该字段数据类型，发现是对text类型字段做了replace操作会导致乱码
