問題產生

    hadoop目錄下，執行下面語句啟動namenode，jps發現namenode啟動失敗

sbin/hadoop.daemon.sh start namenode

問題解決

       （1）Hadoop namenode、datanode、secondarynamenode節點的日子檔案在Hadoop根目錄 logs/下。日誌命名規則為hadoop-使用者名稱-節點名-域名.log尋找namenode節點的日誌，比如我的使用者名稱hadoop，我要找namenode節點，我的域名為hadoop.fang.com。所以我將下面的hadoop-hadoop-namenode-hadoop.fang.com.log複製到我的windows共享資料夾下，來檢視日誌檔案。

    （2）使用cp srcFile destFile 命令將日誌檔案複製到共享資料夾下。 然後開啟最近一次啟動時間的日誌檔案。如下圖。由圖中異常原因Does not contain a valid host:port authority: 0.0.0.0.:50070。可知，是配置etc/hadoop/hdfs-site.xml 的dfs.http.address屬性出錯。多了一個 0.0.0.0. 末尾多了一個點。 配置ip的就兩個檔案還有一個是etc/hadoop/core-site.xml。問題解決
