Hadoop/hdfs command wrapper
As Hadoop command has been deprecated this module will default
to use hdfs command and fall back to hadoop if it is not found
In order to prevent random execution the module name is checked
Follows hadoop command template:
hadoop module -command args
E.g.: hadoop dfs -ls /
