Apache nifi未啓動

Question

我試圖在8號窗口機器上啓動Apache nifi版本1.2.0。它曾經正常啓動。重新啓動系統後，nifi完全沒有啓動。我有檢查狀態它繼續得到「Apacha Nifi沒有運行」。

下面是nifi.bootstrap.log文件記錄： - 從nifi.app.log

谷歌搜索後這個錯誤「引起的：java.io.IOException：預期會讀取'1'的哨兵字節，但得到值'0'，而不是」我發現這個錯誤表示部分寫入回購。

以下是一些您可以檢查/嘗試將Dataflow重新聯機的功能;

• 檢查，如果你的dsks不是完整
• 你啓動nifi使用相同的用戶？你是否以管理員權限運行它？
• 您可以備份/移動您的存儲庫，並嘗試使用空存儲庫啓動Nifi，您仍然可以在那裏獲得數據流，但是任何在關機時正在處理的文件都將消失。

你能試試嗎？
