问题描述
我正在尝试使用lastq的Sqoop增量从DB2数据库导入表。该表具有Timestamp类型的列，这是im使用的检查列。我想先导入整个表，然后再导入任何最新的修改，因此我将last-value设置为0。下面是命令：
注意：updateTS列中的某些值为“ 1/1/0001 12:00:00”
sqoop import --connect "jdbc:db2*****************" --username **** --password ***** --driver com.ibm.db2.jcc.DB2Driver --table my_table --m 20 --split-by col1 --target-dir /user/employ/sqoop_dir --check-column updateTS --incremental lastmodified --last-value 0
执行上述命令时，出现以下错误

如果我只是简单地导入而没有增量lastmodified条件，则导入成功。
sqoop import --connect "jdbc:db2*****************" --username **** --password ***** --driver com.ibm.db2.jcc.DB2Driver --table my_table --m 20 --split-by col1 --target-dir /user/employ/sqoop_dir
但是，现在格式为20/22/2002的updateTS列现在转换为纪元时间戳。
我该如何解决这两个问题？
