u能請說如何檢查做名節點運行。？你是否希望我停止並檢查通知，或者有什麼方法可以檢查它是否停止服務 – Surya

沒有名稱節點沒有在我的本地運行，可以幫助我做到這一點。下面是詳細信息** [迪夫亞@本地的hadoop] $ /home/Divya/hadoop/bin/stop-all.sh 停止JobTracker的本地主機：停止的TaskTracker 沒有NameNode會停止本地主機：停止數據節點本地主機：停止secondarynamenode [Divya @ localhost hadoop] $ ** – Surya

@ user2499617請給我看看你的NameNode日誌。看起來像你的配置有問題。 – Tariq

檢查hadoop守護進程服務是否正常運行。以root身份使用JPS命令檢查它們是否正常運行。確保集羣已正確設置。

jps沒有安裝在我的機器上，在它上面工作，一旦完成就會讓你知道，有沒有其他方法可以查看日誌而不是JPS命令 – Surya

如果它對將來的任何人都有幫助，jps can在這裏找到： $ JAVA_HOME/bin/jps 這個問題更詳細地討論它：http://stackoverflow.com/questions/11738070/hadoop-cannot-use-jps-command – Aditya

jps在我的Ubuntu工作，但不在fedora –

來解決它的最好方法是

檢查Hadoop的守護程序正確使用JPS命令運行。如果沒有，你將不得不格式化使用

斌/ Hadoop的名稱節點名稱節點-format這裏
