Get a few lines of HDFS data

Question

I am having a 2 GB data in my HDFS.

Is it possible to get that data randomly. Like we do in the Unix command line

cat iris2.cs         


        

Answer 1

Write this command

sudo -u hdfs hdfs dfs -cat "path of csv file" |head -n 50

50 is number of lines(this can be customize by the user based on the requirements)
