我已使用此命令添加了一组要抓取的种子
./ bin / crawl / largeSeeds 1 http://localhost:8983/solr/ddcd 4
对于第一次迭代，所有命令（注入，生成，获取，解析，更新表，索引器和删除重复项）都已成功执行。 对于第二次迭代，＆＃34; CrawlDB更新＆＃34;命令失败（请参阅错误日志以供参考），因为此命令失败，整个过程终止。

请告知。
答案 0 :(得分：1)
我使用相同的技术时遇到了完全相同的问题。
我通过更改hbase-common-0.98.17-hadoop2.jar中的文件HConstants.java解决了这个问题（在nutch：nutch / build / lib和hbase：/ hbase / lib中）。
我删除了这一行：
public static final short MAX_ROW_LENGTH = Short.MAX_VALUE;
并添加了这一行：
public static final long MAX_ROW_LENGTH = Long.MAX_VALUE;
现在，它就像一个魅力。
请告诉我，如果它也在运行，或者你需要帮助。
