PredictionIO PIO狀態：動物園管理員存在失敗

我通過安裝PredictionIO $的bash -c 「$（捲曲-s https://install.prediction.io/install.sh）」PredictionIO PIO狀態：動物園管理員存在失敗

，當我做了PIO狀態，它顯示以下信息：

正如https://docs.prediction.io/resources/faq/的建議，我試圖通過$〜/ PredictionIO /供應商/ HBase的-XYZ /斌/ start-hbase.sh啓動HBase的，但仍是同樣的錯誤。

我可以嘗試哪些其他解決方案？我需要手動安裝zookeeper嗎？（我認爲快速安裝會安裝它）。謝謝！

您應該檢查$ PIO_LOG_DIR下的pio.log以獲取更多信息 –

這聽起來像HBase尚未正確初始化。先嚐試做pio-stop-all然後pio-start-all，然後再嘗試pio status。如果這不起作用，請繼續並再次運行pio-stop-all，然後通過鍵入以下命令ps aux | grep hbase來查找正在運行的HBase實例，然後關閉正在運行的相應HBase實例（使用kill -9 <PID>）。再次輸入pio-start-all後，您應該可以運行pio status，而不會出現前面提到的錯誤。

----編輯-----

既然你剛安裝PredictionIO，運行pio-start-all應該足夠了。但是，根據我的經驗，如果您使用的是HBase，則可能會遇到必須按上面所述手動殺死該進程的情況。

感謝Marco！我一直跟隨你的建議，直到'皮奧地位'。但是，在那裏顯示相同的錯誤消息。任何線索？ – Jia

預測-IO完全失去了自從Oracle購買以來的陰謀和任何可行的產品！沒有任何工作了.. actionML端口也被打破。我建議開始尋找ML-Toolkit的其他地方

這是真的，只是一個更正，Salesforce購買了它們，而不是Oracle。 –

根據您的情況睡幾秒（100？）。「等待HBase啓動10秒鐘」並不總是足夠長。我在啓動腳本中儘可能晚地執行pio狀態以節省時間（無需睡眠）。然後，pio身份將始終成功。
