Sqoop连接问题

Question

我正在尝试使用sqoop命令从Oracle查看表，并且该表会错误地弹回。

import requests
webserver = 'http://stev.oapd.inaf.it/cgi-bin/cmd'

# Returns the landing site
r = requests.get(webserver, data={'submit_form': 'Submit'}).text
# Returns an empty string
r = requests.get(webserver, params={'submit_form': 'Submit'}).text
# Returns an empty string
r = requests.post(webserver, data={'submit_form': 'Submit'}).text
# Returns the landing site
r = requests.post(webserver, params={'submit_form': 'Submit'}).text

任何想法都会是什么问题。顺便说一下，我检查了oracle Ip地址并建立了端口
