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

I was using tail and cat for an avro file on HDFS cluster, but the result was not getting printed in correct encoding. I tried this and worked well for me.

hdfs dfs -text hdfs:///part-m-00000.avro | head -n 1

Change 1 to higher integer to print more samples from avro file.
