该数据库的所有日期都以gmt为单位，而sqoop会自动获取本地（亚洲/加尔各答）的增量更新。
它可能是从jvm中获取的，但我需要它对某些作业使用gmt，对其他作业使用local。我该怎么办？

讨论同样的问题。有什么解决办法吗？线程中给出的解决方案对我来说并不真正有效。
以下是我在sqoop工作的经验：

sqoop job -D oracle.sessionTimeZone=GMT -D mapred.child.java.opts=" -Duser.timezone=GMT" --meta-connect jdbc:hsqldb:hsql://FQDN:16000/sqoop --create JOB_NAME -- import --driver com.mysql.jdbc.Driver --connect jdbc:mysql://IP/DB?zeroDateTimeBehavior=convertToNull --username root --password 'PASSWORD' --table TABLE_NAME--incremental lastmodified --check-column updated_at --last-value 0 --merge-key entity_id --split-by entity_id --target-dir LOCATION_SPECIFIED --hive-database Magento --hive-drop-import-delims --null-string '\\N' --null-non-string '\\N' --fields-terminated-by '\001' --input-null-string '\\N' --input-null-non-string '\\N' --input-null-non-string '\\N' --input-fields-terminated-by '\001'
