Hadoop start-all.sh錯誤：無此類文件或目錄

Question

成功創建名稱節點后，嘗試啟動名稱節點時遇到了此問題。 對我來說，似乎正在嘗試登錄到不存在的文件。 如何更改設置以將腳本日志定向到正確的目錄？

bash-3.2$ start-all.sh
starting namenode, logging to /usr/local/bin/../logs/hadoop-Yili-namenode-wifi169-
116.bucknell.edu.out
nice: /usr/local/bin/../bin/hadoop: No such file or directory
localhost: starting datanode, logging to /usr/local/bin/../logs/hadoop-Yili-datanode-
wifi169-116.bucknell.edu.out
localhost: nice: /usr/local/bin/../bin/hadoop: No such file or directory
localhost: starting secondarynamenode, logging to /usr/local/bin/../logs/hadoop-Yili-

Answer 1

嘗試運行which hadoop 。 如果此命令給您輸出，則您的HADOOP_HOME已在.bashrc文件中設置。

如果未設置，則在主目錄中編輯.bashrc文件，並考慮到您的hadoop已安裝在/opt/hadoop ，添加以下語句。 它可能是另一個位置。

HADOOP_HOME=/opt/HADOOP
export HADOOP_HOME
PATH=$PATH:$HADOOP_HOME/bin
export PATH

這將為您提供幫助。
