hive> drop table ml_123;

root使用者無法操作hdfs

有2種解決：

1.修改hdfs引數 dfs.permissions=false

2.賦許可權給root

我選擇的是修改引數

步驟1.

2.重啟HDFS元件，讓其生效。

3.重啟成功後，shell重新登入，root執行也ok

Permission denied: user=root, access=WRITE, inode="/":hdfs:supergroup:drwxr-xr-xhd

問題分析開始仔細的觀察了這個錯誤的詳細資訊，看到user=Administrator, access=WRITE。這裡的user其實是我當前系統（執行客戶端的計算機的作業系統）的使用者名稱，實際期望這裡的user=hadoop（hadoop是我的HADOOP上面的使用者名稱），但是它取的是當前

1.問題描述在hdfs上建立目錄報錯： mkdir: Permission denied: user=root, access=WRITE, inode="/":hdfs:supergroup:drwxr-xr-x 2.問題原因 hdfs上許可權限制，root是沒有許可權的。除非取

hadoop中執行操作時錯誤提示如下： Permission denied: user=root, access=WRITE, inode="/":hdfs:supergroup:drwxr-xr-x 許可權問題，需要修改目標操作的許可權，或者修改操作的使用者。可以用

MYSQL重置密碼 MySQL ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password:YES)

一般這個錯誤是由密碼錯誤引起，解決的辦法自然就是重置密碼。假設我們使用的是root賬戶。 1.重置密碼的第一步就是跳過MySQL的密碼認證過程，方法如下： #vim /etc/my.cnf(注：windows下修改的是my.ini) 在文件內搜尋mysqld定位
