在多節點集羣中運行Hadoop無法正常工作

我安裝了HDFS並在3臺計算機上工作，然後我嘗試向現有集羣中添加5臺PC，但之後嘗試在主節點上啓動hadoop得到下面提到的這個錯誤。在多節點集羣中運行Hadoop無法正常工作

它清楚地說'FileNotFoundException'和'權限被拒絕'並告訴你路徑。你不能爲自己解決嗎？ –

我會像

sudo touch /usr/local/hadoop/bin/logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

手動創建日誌文件。如果你的路徑是

/usr/local/hadoop/bin/../logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

更好的修復，因爲我在寫第一行。

然後更改文件的權限：

sudo chmod 750 /usr/local/hadoop/bin/logs/hadoop-hduser-namenode-dellnode1.pictlibrary.log

，然後再試一次。它應該這次工作;-)
