Nutchを使用して複数のWebサイトを正常にクロールして2つのセグメントを作成しました。私はSolrサービスもインストールして起動しました。Apache Nutch 1.12とSolr 5.4.1の統合に失敗しました
しかし、これらのクロールされたデータをSolrにインデックス付けしようとすると、そのデータは機能しません。
私は、このコマンドを試してみました：
bin/nutch index http://localhost:8983/solr crawl/crawldb/ -linkdb crawl/linkdb/ crawl/segments/*
出力：
The input path at crawldb is not a segment... skipping
Segment dir is complete: crawl/segments/20161214143435.
Segment dir is complete: crawl/segments/20161214144230.

出力：

これらの前に、ファイルを/Nutch/solr-5.4.1/server/solr/configsets/data_driven_schema_configs/confにコピーし、提案通りにmanaged-schemaと名前を変更しました。
私の考えられる間違いはありますか？前もって感謝します！
