Permission denied in copying the input file from local to HDFS

Question

I am unable to put file into the HDFS. Whenever I try to execute put command, I receive a permission denied error. I have tried giving all read write execute permissions to the input file, but the problem still stands.

This is the command I executed. I am currently in hduser which has hadoop installed in it:

hadoop dfs -put /home/hduser/input /

The error I receive is the following:

WARNING: Use of this script to execute dfs is deprecated. WARNING: Attempting to execute replacement "hdfs dfs" instead. put: /input._COPYING_ (Permission denied)

Answer 1

According to the documentation of the put command you should use it like the following:

hadoop fs -put /path/to/localfile /home/hduser/input

where:

1. /path/to/localfile is the path on local FS where is the file you want to put on HDFS
2. /home/hduser/inputis the HDFS destination folder path
