Subject [jira] [Commented] (HBASE-11467) New impl of Registry interface not using ZK + new RPCs on master protocol
Date Tue, 12 Aug 2014 21:26:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14094704#comment-14094704

ryan rawson commented on HBASE-11467:
-------------------------------------

Having an extra RPC to figure out who you're talking to isn't horrifyingly bad. 

Thinking broader, how does SSH do this?  Could we emulate that?  I believe that in SSH you
can tell it via config that this key should be used for this host(s), and absent that, it
walks thru the set of keys it has at its disposal.

What is the simplest approach for the user?  Magic strings tend to be not liked much

> Currently there' only one implementation of Registry interface, which is using ZK to
get info about meta. Need to create implementation which will be using  RPC calls to master
the client is connected to.
> Review of early version of patch is here: https://reviews.apache.org/r/24296/
