スワップコア（REINDEX - > LIVE）の後、私のスレーブマシンは破損しています

質問

ここでは非常に奇妙な問題があります、私は私のSOLRアーキテクチャをセットアップしました。こちらのとすべてがうまく機能します。（テスト）セットアップは次のとおりです。

solr setup

2つのコアを持つ1つのSOLRマスター（ReIndex and Live）

2つのコア（ReIndex and Live）を持つ1つのSOLRスレーブ

PollInterval 00:00:02
に設定
最適化またはコミット後の複製

Ubuntu（11.10）バージョン1.4.0の下でSolrを実行します。

プロセス

プロセス全体がこのようになります。

マスターReIndex Core
we ReIndex Core を無効にする>
DataImportHandlerを開始する10.000ドキュメントのパースでMySQLデータをインポートします（Long MySQLロックを防ぐため）

遅くDataImportHandlerが行われます（400万レコード）マスター

でレプリケーションを有効にします。

スレーブはマスター

から新しいReIndexコアを取得します

href="http://localhost:8080/solr/reindex/Replication?Command=Details" REL="NOFOLLOW NOREFERRER">フェッチが行われています。 a コアスワップ

完全な再構築後、ライブコアには5000ドキュメントとReIndex Core 20000があるとしましょう。

（間違った）結果

スワップ後、これは結果です。

MASTER：LIVE（20000）、Reindex（5000）スレーブ：ライブ（20000）、Reindex（20000）

スレーブが彼のReIndexコアをライブコアにコピーするように見えますが、マスターのようにReIndexコアを使ってライブコアを交換しません。問題は、スレーブがそれが新しいと考えることがそれからマスターを考えると考えると、結果はレプリケーションがReIndex Coreで死んでいます。

スワップが発行された直後のいくつかのログメッセージがあります：

ステップ6すべてが手動ですべてをすると大丈夫です。コアスワップの後にすべてが折りたたみます。

誰かが私を助けたり、間違っていることを私に言ったりすることができることを願っています。コアスワップをすると複製を無効にする必要がありますか？どんなヒント？

解決

私はこの問題を解決することができた、問題は私のコアの両方が同じデータディルを使っていたということでした。solr.xmlファイルのDataDIRを両方の異なるディレクトリに設定することで、問題が解決しました！
