無法在Windows上運行Apache nifi

Question

在我目前的項目中，我一直在使用apache nifi進行一些實驗目的。 當我第一次配置。 nifi運行完美（當我輸入http://localhost:8080/nifi/時，我能夠看到Google Chrome上的畫布，工具欄）。但是，重啓計算機一次後，我無法運行它。

當我鍵入nifi.0.7.0\bin\run-nifi.bat命令時，我在控制檯上看到以下消息。

您能否告訴我這是什麼問題？我怎麼能解決這個問題？

更多的詳細信息，的nifi-app.log內容如下：

和nifi-user.log是空。

當我嘗試撥打localhost:8080/nifi/時，我看到以下內容。

Answer 1

嘗試檢查配置文件是否具有值「nifi.sensitive.props.key =」以下鍵「。 如果它是空的，請設置一個鍵，如示例「nifi.sensitive.props.key = 132134」。

如果您仍然處於煩惱狀態，請觀看此視頻，應該有所幫助。 https://www.youtube.com/watch?v=DDd6KayUHt8

一切順利。

Answer 2

除了之前的評論幫助我解決了這個問題之外，您還需要花費一點時間，因爲這裏已經討論了https://community.hortonworks.com/questions/107192/nifi-web-ui-not-working-facing-error-err-connectio.html。事實上，在啓動Nifi之後，Web界面並不能立即到達，Nifi需要一段時間來初始化所有內容。您可以通過訪問名爲：nifi-app.log的日誌文件來追蹤Nifi的執行情況，您可以在NIFI_HOME/logs中找到它。 我認爲消息：org.apache.nifi.NiFi控制器初始化耗時132792678105納秒（132秒）是Nifi Web界面可以使用的好兆頭。
