我正在运行nutch来抓取并索引solr。运行bin / nutch时，我收到以下错误：
Indexer: java.io.FileNotFoundException: File file:/opt/nutch/crawl/linkdb/current/linkdb-merge-1124746471/data does not exist.

所以，它抱怨：/ opt / nutch / crawl / linkdb / current / linkdb-merge-1124746471 / data不存在。 但是，/ opt / nutch / crawl / linkdb / current / linkdb-merge-1124746471 / part00000 / data确实存在。 这种差异怎么会发生？即，我在哪里可以配置索引过程，以便索引器可以找到上一步创建的文件？
非常感谢任何帮助或提示！

需要删除文件夹.../linkdb/current/linkdb-merge-1124746471/。它是来自“invertlinks”或“mergelinkdb”作业的临时文件夹。它不在正确的地方：应该是.../linkdb/linkdb-merge-1124746471/。如果使用.../linkdb/调用作业而不是.../linkdb/current/，则可能会发生这种情况，因为linkdb的命名方式没有限制。
