指定輸出路徑我新的R輸入語言。我與R.火花寫一個程序我想輸出保存到HDFS path.I嘗試sink方法

sink("/user/new/output/test.txt") 

但它拋出一個錯誤。任何幫助將不勝感激。

確切的錯誤信息是

error in file(file, ifelse(append, "a", "w")) : 
cannot open the connection 
Calls: sink -> file 
In addition: Warning message: 
In file(file, ifelse(append, "a", "w")) : 
cannot open file '/user/new/output/text.txt': No such file or directory 
Execution halted 

Answer 1

當含有該文件的目錄test.txt要下沉到不存在，則表示此錯誤。您可以在R內創建它（如果您有寫入權限）：

dir.create("/user/new/output/test.txt")
