次のコマンドを使用して、Nuch でクロールしたデータのインデックスを作成しようとしています。
bin/nutch index -D solr.server.url="https://gateway.watsonplatform.net/retrieve-and-rank/api/v1/solr_clusters/sc97b4177a_600f_4040_9309_e632c116443f/solr/localWebCollection/" -D solr.auth=true -D solr.auth.username="USER" -D solr.auth.password="PASS" final/crawl/crawldb -linkdb final/crawl
エラーは発生しませんが、実行すると数秒後に終了し、インデックスが作成されません。これが私のログです：

これを修正してデータにインデックスを付けるにはどうすればよいですか? Bluemix Retrieve and Rank Service の URL ですが、Apache Solr の上に構築されているので、Nutch と Solr のスキーマが一致していれば使用できると思います。右？
