Question

我正在尝试使用Sqoop从Sybase导入数据。从日志我可以说我已经成功地做了一个连接。但是我的工作没有给我一些Sybase的Sql异常。我不主要在Sybase上工作不能用这个错误挖掘出来。我的只有一个来源是Sybase。

我使用了以下命令：

sqoop import --verbose \
--driver com.sybase.jdbc3.jdbc.SybDriver \
--connect jdbc:sybase:Tds:nyhostx123.sm.com:13290/DATABASE=tempdb \
--table tempdb..mit \
--split-by sipid \
--fields-terminated-by ',' \
--target-dir /home/DEVTEST/sqoop_mit \
--username user01 \
-m 1 \
-P

Answer 1

我认为问题在于--table参数。 Sqoop期待纯表名，但你似乎传递了额外的值“tempdb ..”（我猜它是一个db名称？）。你介意只用“ - 表格”来试试吗？
