This is the error I have been getting while running the hadoop jar command though the input file is existing in that path which I checked in the browser.

Can anyone help me please?

Answer 1

确保/ usr / hdfs /是HDFS文件路径，而不是本地文件系统路径。

Answer 2

尝试执行hadoop fs -ls /usr/hdfs/Deliverydetails.txt如果不存在，则您的文件位于本地文件系统中，而不是hadoop文件系统中
