Apache Nutch 跳过 URL 和截断

Question

在我的 nutch-site.xml 中，我添加了以下内容以停止截断；但是，在获取过程中，出现以下错误。我希望它停止截断并提供我需要的结果，我假设 -1 值可以实现。我正在使用 2.2.1 版。有什么想法吗？

<property>
    <name>http.content.limit</name>
    <value>-1</value>
    <description>The length limit for downloaded content using the http
        protocol, in bytes. If this value is nonnegative (>=0), content longer
        than it will be truncated; otherwise, no truncation at all. Do not
        confuse this setting with the file.content.limit setting.
    </description>
</property>

Answer 1

我通过删除 nutch-site.xml 中的 http.content.limit 部分并添加 parser.skip.truncated 并将其设置为 false 来解决这个问题。

<property>
    <name>parser.skip.truncated</name>
    <value>false</value>
    <description>Boolean value for whether we should skip parsing for truncated documents. By default this
        property is activated due to extremely high levels of CPU which parsing can sometimes take.
