[jira] [Commented] (DRILL-4238) Allow custom messages to be sent on control channel

    [ https://issues.apache.org/jira/browse/DRILL-4238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15076736#comment-15076736 ]

    DRILL-4238: Add a custom RPC interface on the Control channel for extensible communication between bits.

    Adds two new interfaces:
    
    - Controller.registerCustomHandler() to register a custom message handler
    - ControlTunnel.getCustomTunnel() to send and receive via a custom tunnel (and communicate with custom handlers).
    
    Simple test shows sending and receiving structured messages as well as structured + unstructured messages. As an extensibility point, real uses will come from StoragePlugins, etc.

> Storage Plugins may have the need to communicate between nodes. Rather than implementing a new RPC layer for that purpose, we should add support for a custom tunnel to be piggy-backed on the existing Control RPC layer.
