[jira] [Created] (HADOOP-11518) Prefix-based per-RPC server configuration

Kihwal Lee created HADOOP-11518:
-----------------------------------

             Summary: Prefix-based per-RPC server configuration
                 Key: HADOOP-11518
                 URL: https://issues.apache.org/jira/browse/HADOOP-11518
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ipc
            Reporter: Kihwal Lee


If a process runs multiple RPC servers, there is no way to individually set their IPC parameters beyond what's supported by the RPC Builder.  If a configuration is shared among many nodes, this is more problematic. 

In this jira, a prefix-based per-server configuration is proposed.  When an RPC server is built, a prefix can be specified, which will then be prepended to keys when retrieving configured values.  There will be an option to fall-back to using the key without the prefix when no value is found with the prefix, thus making this feature compatible with the current way of configuring servers.
