Question

我正在尝试使用Nutch 1.7抓取一些网址，但我正面临

身份验证问题和
连接被拒绝例外。
根据日志，我可以看到它正在尝试使用NTLM进行身份验证，但之后显示“需要重定向”并最终释放连接...（可以在logpart-1中看到）

根据

http://wiki.apache.org/nutch/HttpAuthenticationSchemes#A_note_on_NTLM_domains

我已在httpclient-auth.xml文件中设置了auth-configuration：
httpclient和nutch-site.xml
中定义的nutch-default.xml属性
plugin.includes 协议 - （HttpClient的| HTTP）| urlfilter-
正则表达式| parse-（文|全文|蒂卡）|指数 - （更多|基本|锚）|索引-的Solr | scoring-
OPIC | urlnormalizer-（通|正则表达式|基本）
还在nutch-site.xml。
中定义了auth配置文件
http.auth.file HttpClient的-auth.xml “protocol-httpclient”插件的身份验证配置文件。

但我没有成功！

我没有以正确的方式配置身份验证，或者我错过了什么？

任何人都可以帮我在Nutch中使用正确的身份验证配置吗？

附加完整hadoop.log：

我收到的其他几个链接

处理请求时捕获到I / O异常（java.net.ConnectException）：连接被拒绝：连接

我不在任何代理后面，我仍然关闭了系统中的所有防火墙设置。不知道为什么我得到连接拒绝异常。

在这里，我也无法找到连接拒绝例外的确切原因。

请帮助我理解这个案例的确切问题。

Attaching the complete hadoop.log！

logPart2-connection拒绝了。

Answer 1

1）从日志中可以清楚地看到您的特定网站上的NTLM身份验证失败。

此处您必须先检查用户名/密码。

然后是Auth Basic / NTLM /的方案然后是您要验证的端口

如果您验证这3点并使用正确的值，那么您的身份验证问题应该得到解决......

使用nutch进行爬网时，身份验证和连接被拒绝错误
