namenode起始錯誤

當我嘗試在主節點上啓動hadoop時，我得到以下輸出並且namenode未啓動。namenode起始錯誤

[[email protected] ~]$ start-dfs.sh 
starting namenode, logging to /usr/local/hadoop/bin/../logs/hadoop-hduser-namenode-dellnode1.library.out 
dellnode1.library: datanode running as process 5123. Stop it first. 
dellnode3.library: datanode running as process 4072. Stop it first. 
dellnode2.library: datanode running as process 4670. Stop it first. 
dellnode1.library: secondarynamenode running as process 5234. Stop it first. 
[[email protected] ~]$ jps 
5696 Jps 
5123 DataNode 
5234 SecondaryNameNode

您是否檢查過Namenode日誌（我認爲在$ HADOOP_HOME/logs中是默認的）？大多數情況下，這裏的信息非常清晰。 – Pieterjan

你能分享你的日誌文件嗎？ – Tariq

而不是使用jps（只顯示當前用戶的進程），你可以運行一個'ps axww | grep hadoop「（dellnode1和dellnode2）並將該輸出粘貼回原始問題 –

「先停下來」。

首先調用stop-all.sh
類型JPS
呼叫start-all.sh（或start-dfs.sh和start-mapred.sh）
類型jps（如果namenode不會出現類型「hadoop namenode」並檢查錯誤）

典型的輸出應該是什麼樣的？我只得到'15845 Jps'。 http://unix.stackexchange.com/questions/257279/validate-start-dfs-sh – gsamaras

此方法已棄用。所以 stop-dfs.sh， stop-yarn.sh， start-dfs.sh， start-yarn.sh 優先 –

根據在較新版本的hardoop上運行「stop-all.sh」，這已被棄用。您應該改用：

stop-dfs.sh

和

stop-yarn.sh

感謝的使用，這個工作對我來說 –

今天，在執行生豬腳本我在問題中提到了同樣的錯誤：

starting namenode, logging to /usr/local/hadoop/libexec/../logs/hadoop-training-namenode-localhost.localdomain.out 
localhost: /home/training/.bashrc: line 10: /jdk1.7.0_10/bin: No such file or directory 
localhost: Warning: $HADOOP_HOME is deprecated. 
localhost: 
localhost: starting datanode, logging to /usr/local/hadoop/libexec/../logs/hadoop-training-datanode-localhost.localdomain.out 
localhost: /home/training/.bashrc: line 10: /jdk1.7.0_10/bin: No such file or directory 
localhost: Warning: $HADOOP_HOME is deprecated. 
localhost: 
localhost: starting secondarynamenode, logging to /usr/local/hadoop/libexec/../logs/hadoop-training-secondarynamenode-localhost.localdomain.out 
starting jobtracker, logging to /usr/local/hadoop/libexec/../logs/hadoop-training-jobtracker-localhost.localdomain.out 
localhost: /home/training/.bashrc: line 10: /jdk1.7.0_10/bin: No such file or directory 
localhost: Warning: $HADOOP_HOME is deprecated. 
localhost: 
localhost: starting tasktracker, logging to /usr/local/hadoop/libexec/../logs/hadoop-training-tasktracker-localhost.localdomain.out

因此，答案是：

[[email protected] bin]$ stop-all.sh

，然後鍵入：

[[email protected] bin]$ start-all.sh

的問題將得到解決。現在你可以用mapreduce運行豬腳本！
