cannot access webhdfs from openmind

[DongZhaoYu]

When putting data from openmind to webhdfs, the returned location header is ：

http://xxx.xxx.xxx.xxx/a/xxx.xxx.xxx.xxx/50075/webhdfs/v1/user/code/code.py?op=CREATE&user.name=xxx&namenoderpcaddress=xxx.xxx.xxx.xxx:9000&createflag=&createparent=true&overwrite=false

webhdfs client cannot use this url to put data. the error is :
user.name=user: command not found

The cause of this problem:
the request is received by pylon and pylon cannot handle it.

We need to first confirm this address is correct. If it is correct, we should fix pylon to support this.

@Gerhut , please have a check.

return 307 $scheme://$http_host/a/$1:$2/$3;

and you should add quotes around the URL when you access it in shell using curl or something else

I'll open a pull request to fix this.
