即时尝试从配置单元导出数据到一个mssql服务器，我知道sqoop和sql服务器都可以，因为我可以导出另一个没有问题的表。使用sqoop从配置单元导出到sqlsrver
，即时通讯得到的错误是：

使用导出数据的命令IM是：
sqoop export --verbose --connect "jdbc:sqlserver://xx;database=xx;username=xx;password=xx" --export-dir /user/hive/warehouse/xx/twitter_bulk2/ --table StageFlumeTweets --input-fields-terminated-by ','
与数据文件只是一个tweetid和像这样的文本：
