我正在尝试将表从RDBMS（MYSQL或AS400）导入到Hive。 sqoop操作成功，但是在将数据导入到Hive时抛出异常。
下面是跟踪日志：

我的sqoop脚本：
sqoop import \
--libjars /usr/lib/sqoop/jt400-6.4.jar \
--driver com.ibm.as400.access.AS400JDBCDriver \
--connect "jdbc:as400://172.17.129.30/DB" \
--username xxxxxxx\
--password xxxx@9xxxxx \
--table ROH319P4 \
--columns "ITMC19, ITMD19, PIXT19, SOUT19, USER19, DATE19, TIME19, TERM19" \
--target-dir /user/hive/test100 \
--fields-terminated-by "," \
--hive-import -m 1
我什至检查了日志，重新启动了配置单元，但无法解决。奇怪的是，相同的代码可以正常工作，但是现在抛出异常。
