How to list files in hadoop?

Hi,

Hadoop uses its own file system which is know as Hadoop File System or HDFS.

Hadoop provides commands to interact with the HDFS. To list down all the file in a directory you can use the following command:

hadoop fs -ls /

Above command lists all the files from the root of HDFS.

Sample output:

hdfs@hadoop1:/home/deepak$ hadoop fs -ls /
Found 11 items
drwxrwxrwx   - yarn   hadoop          0 2017-05-13 18:33 /app-logs
