我尝试使用sqoop将数据从本地postgres导入到s3。我的命令是
sqoop import --connect jdbc:postgresql://localhost/postgres --username username --password password --table table --driver org.postgresql.Driver --target-dir s3://xxxxxxxx/data/ -m 1```
我能够导入到本地目录，但是对于s3存储桶失败了。
日志发布如下。

真的不确定如何向日志添加详细信息，或者如何使日志看起来不像代码，所以它不会要求更多细节。遗憾。
