[jira] [Updated] (HADOOP-10376) Refactor refresh*Protocols into a single generic refreshConfigProtocol

     [ https://issues.apache.org/jira/browse/HADOOP-10376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

------------------------------

    Attachment: HADOOP-10376.patch

Uploaded new patch.

I decided to add support for multi registration again. The reasoning is that this feature simplifies things by allowing any class to register as a refresh handler, even if it doesn't know about its server's port (eg what ID to register itself as), and the whole benefit to having a registry like this is to allow for a more decentralized approach.

> There are starting to be too many refresh*Protocols We can refactor them to use a single protocol with a variable payload to choose what to do.
> Thereafter, we can return an indication of success or failure.
