Some Python code to help you have fun with Hadoop. Unmaintained. If you pip install snakebite it's possible that this code will work for you too!
Example code:
import hdfs_fun
fun = hdfs_fun.HDFSFun()
blocks = fun.find_blocks('/wikipedia.csv')
fun.print_blocks(blocks)will output something like:
Bytes | Block ID | # Locations | Hostnames
