Python function to run hdfs commands

+1 vote

I am trying to write a function which will run hdfs commands.

I have got this far:

import subprocess

def run_cmd(args_list):
    proc = #Here should be the function.

    (output, errors) = proc.communicate()

    if proc.returncode:

        raise RuntimeError('Error running command')

    return (output, errors)
