Following redirects with curl

[Kevin Minder <ke...@hortonworks.com>]

Hey Everyone,

I was writing some docs and bemoaning the need to document two curl 
commands for every WebHDFS file operations.  I was complaining to 
myself, "Why can't curl just follow the redirects?"  Then I had one of 
those moments when you realize you're an idiot, of course curl can 
follow redirects.  The two commands below PUT and GET a file via 
Knox/WebHDFS in a single command.  The key is the -L switch.

curl -i -k -u guest:guest-password -L -T README -X PUT 
'https://localhost:8443/gateway/sandbox/webhdfs/v1/user/guest/test/input/README?op=CREATE'
curl -i -k -u guest:guest-password -X GET -L 
'https://localhost:8443/gateway/sandbox/webhdfs/v1/user/guest/test/input/README?op=OPEN'

Enjoy, I know I will!
Kevin.
