我正在部署帶有VFS集羣的Drools Workbench。我遵循了「VFS-CLUSTERING」部分中的Drools-6文檔中定義的步驟以及以下鏈接。但我的存儲庫是否未同步Drools Workbench - VFS存儲庫集羣 - 工作臺資產未同步

但得到以下動物園管理員例外。
NoNode爲/ jbpm的羣集/ INSTANCES/nodeOne_11 /消息/ df7cda63-979b-47b2-AC9A-f2b218cb188
問題在工作臺-A創建 BPMN過程是沒有得到與工作臺-B同步。以下是項目資產差異的屏幕截圖。連接在「ServerAssets.png」

動物園管理員設置
Changes done only in zoo.conf
1. dataDir = /zooDir/zookeeper (Not sure where this directory gets created as I could not find it in $zookeeper_home/)
2. clientPort = 2199
