AWS：从s3使用复制命令到redshift时未插入任何内容

Question

I have big data in s3 and have to move into redshift, and have one table in redshift. Since I use python, I wrote python script and use psycopg2 to connect redshift. I succeeded to connect to redshift, but I failed to insert data from s3 to redshift. I checked dashboard in aws website and found that redshift received a query and it loads something, but it does not insert anything and the time consumed for this process is too long like over 3 minutes. There is no error log so I can't find what is the reason.

Is there any possible cause for this?

EDIT added copy command I used.

copy table FROM 's3://example/2017/02/03/' access_key_id '' secret_access_key '' ignoreblanklines timeformat 'epochsecs' delimiter '\t';

尝试查询stl_load_errors表，该表具有有关数据加载错误的信息http://docs.aws.amazon.com/redshift/latest/dg/r_STL_LOAD_ERRORS.html

select * from stl_load_errors order by starttime desc limit 1
