Using Nginx to proxy Hadoop services web UI:

User --> (https) Nginx --> Hadoop {DATA NODES YARN web UI, webhdfs ...}

When I curl to https://HOST/webhdfs/..... the webhdfs server redirect to data node:

HTTP/1.1 307 TEMPORARY_REDIRECT
Location: http://DATA-NODE-1:50075/webhdfs ...

Where DATA-NODE-1 is a DNS/IP "intern" to Hadoop cluster so end-user cannot access it.

I want to rewrite the Locationheader sent by proxied backend to:

https://50075.DATA-NODE-1.HOST/webhdfs... (PORT.SERVICE.HOST)

So Nginx can handle it, and do the proxy stuff.

Is it possible with Nginx modules or do I need a LUA/Perl script?
