我正在尝试使用sqoop从db2数据库导入一个表。该表有一个timestamp类型的列，它是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，因此我将最后一个值设置为0。命令如下：
注：updatets列中的某些值是“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

当我执行上述命令时，我得到以下错误

另外，如果我只是在没有增量lastmodified条件的情况下导入，那么导入是成功的。

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，格式为20/22/2002的updates列现在转换为epoch timestamp。
如何解决这两个问题？
