【问题描述】：

我正在集成 Nutch、Hbase 和 Solr。

我配置了 Nutch、Hbase 和 Solr，并且还为 Crawling the Websites 做了操作，但同时按照这个将 Nutch 与 Solr 集成 Integrating Nutch 2.3, HBase and Solr，我执行了命令 /opt/solr-4.8.1/examples 中的 java jar start.jar。

进程已启动，但执行需要花费大约 10 天的时间，现在它仍在运行。

我无法找出它出了什么问题。任何人都可以提出什么问题以及如何解决。

以下是日志文件的一些细节。

【问题讨论】：

哇，你怎么能等上10天……
我开始从事其他工作并保持集成过程不变。
你可以查看solr的日志看看是怎么回事。
是的，我检查了日志，每次 Solr 执行一些操作，例如 org.apache.solr.core.SolrCore; [collection1] webapp=/solr path=/admin/system params={wt=json&_=1463570798133} status=0 QTime=12

【解决方案1】：

最后，我解决了。基本上，java -jar start.jar是下载jar文件的，所以这里不做索引，而是下载Solr 4.8 jars，然后配置它。由于性能原因，我用Solr 5.2.1替换了Solr 4.8现在 Solr 工作正常。
