HADOOP報錯，隨筆

標籤：hadoop   java_home   not be found   報錯   

1、新版本2.4.1中，profile/hadoop-env.sh中均己設定 JAVA_HOME，  java -version也正常。

啟動時報錯：

[[email protected] ~]# start-all.sh

Starting namenodes on []

localhost: Error: JAVA_HOME is not set and could not be found.

localhost: Error: JAVA_HOME is not set and could not be found.

...

starting yarn daemons
starting resourcemanager, logging to /home/lihanhui/open-source/hadoop-2.1.0-beta/logs/yarn-admin-resourcemanager-localhost.out
localhost: Error: JAVA_HOME is not set and could not be found

直接命令列執行export JAVA_HOME=/PATH/TO/JDK也無法解決問題：

最終在   hadoop-2.4.1/etc/hadoop/libexec/hadoop-config.sh  這個設定檔中搜到報錯資訊“JAVA_HOME is not set and could not be found”

於是在這個設定檔中，  export JAVA_HOME=/PATH/JDK

問題得己解決、
