这是我用来为增量导入创建sqoop作业的代码，hdfs中存在已存储数据的文件。我添加了几行以检查sqoop上的增量导入，但是我收到如下错误，请帮助，提前致谢。
sqoop job \
--create incimp \
--import \
--connect "jdbc:sqlserver://<localhost>;database=<db>" \
--username "username" \
--password "password" \
--driver "com.microsoft.sqlserver.jdbc.SQLServerDriver" \
--table "tablename" \
--append --check-column "columnname" \
--last-value "<name>" \
--incremental lastmodified \
--fields-terminated-by ',' \
--target-dir "<hdfs-path>" \
-m 1
