You can use fsck for this purpose
hadoop fsck <HDFS directory> -files -blocks -locations --- Displays what you want

If I push a file into HDFS that runs on a 4 node cluster with 1 namenode and 3 datanodes, how can I view where on the datanodes are the blocks of this file?I would like to view the blocks and their replicas individually. How can I do this?
The answer is very critical for my current task which is halted :) A detailed answer will be highly appreciated.Thank you!
