錯誤，同時運行solrindexer

Question

現在我使用3.6.1和nutch 1.5，它工作正常...我抓取我的網站和索引數據到索爾和使用solr搜索，但兩個星期前它開始不工作... Whene我使用./nutch抓取urls -solr http://localhost:8080/solr/ -depth 5 -topN 100命令它的工作，但是當我使用./nutch抓取urls -solr http://localhost:8080/solr/ -depth 5 -topN 100000，它拋出一個異常，在我的日誌文件中我發現這個..

兩個星期前，它工作得很好...... 有沒有人有類似的問題？

嗨，我剛剛完成抓取和山楂相同的異常，但是當我看我的日誌/ hadoop.log文件，我發現這個..

我希望這將有助於理解這個問題...

Answer 1

隨着您顯示的日誌，我認爲答案將在Solr方面。你應該有一個異常跟蹤，它會告訴你什麼組件停止了處理。如果它在兩週前運行，或者有更改（jar版本？），或者你有一個特定的文檔是一個問題。

如果單個文檔發生問題（嘗試幾個不同的文檔），那麼您可能會改變環境（罐子，屬性等）。如果文檔的一個子集沒有發生但與另一個文檔發生，則可能是特定文檔存在問題（例如編碼錯誤）。

同樣，Solr端堆棧跟蹤將是第一件要檢查的事情。
