Apache Nutch 1.12和Solr 5.4.1集成失败

Question

我已经成功地爬取了几个网站，并使用Nutch创建了两个片段。我也安装并启动了Solr服务。

但当我试图将这些爬取的数据索引到Solr中时，它就不起作用了。

我尝试了这个命令：

bin/nutch index http://localhost:8983/solr crawl/crawldb/ -linkdb crawl/linkdb/ crawl/segments/*

输出：

The input path at crawldb is not a segment... skipping
Segment dir is complete: crawl/segments/20161214143435.
Segment dir is complete: crawl/segments/20161214144230.

还有这个命令：

bin/nutch solrindex http://localhost:8983/solr crawl/crawldb/ -linkdb crawl/linkdb/ crawl/segments/*

输出：

    at org.apache.nutch.indexer.IndexingJob.main(IndexingJob.java:237)

在此之前，我将nutch/conf/schema/xml文件复制到/nutch/solr-5.4.1/server/solr/configsets/data_driven_schema_config/conf中，并按照建议将其重命名为managed-schema。

我可能会犯什么错误？提前道谢！

这是我的圆木

Answer 1

问题是solr、nutch和HBase之间的版本不兼容。这篇文章对我很有用。
