@vsubramanian, I'm afraid this is currently not possible. The only WebHDFS REST api that implements "recursive" query parameter is delete. So if you use recursive with delete, that would work. The ListStatus API here has not implemented any recursive logic. For your use-case, you'll manually need to call curl with op=LISTSTATUS multiple times for each directory after parsing the output. Similar to what "ls -R" Shell command does currently. Hope this helps.
