任何人都可以說沒有在jps中顯示hadoop惡魔的原因？

我使用的是hadoop 2.7.3版本，配置後namenode沒有在jps中顯示。任何人都可以說我給予有關文件的正確權限的原因是什麼。我刪除了/ tmp文件並重新創建了namenode，然後對其進行了重新格式化。在此先感謝。任何人都可以說沒有在jps中顯示hadoop惡魔的原因？

還有另一個進程監聽相同的端口50070，先停止它。

謝謝你，現在工作 – Yasodhara

，如果你不運行它之前格式化HDFS這種情況發生。

運行

hdfs namenode -format

我也這樣做過，在這裏我向你發送日誌文件，如果你能理解，告訴我如何解決這個問題，請參閱上面的plz。我已經盡了一切辦法來解決但不能解決。 – Yasodhara
