Description

WebHDFS needs to expose NN RPC calls to allow users to access HDFS via HTTP / HTTPS.

The current approach is to add REST APIs into WebHDFS one by one manually. It requires significant efforts from a maintainability point of view. we found that WebHDFS is consistently lagging behind. It's also hard to maintain the REST RPC stubs.

There are a lot of values to expose the NN RPC in a HTTP / HTTPS friendly way automatically.
