Subject [jira] [Commented] (HBASE-10504) Define Replication Interface
Date Tue, 08 Apr 2014 18:33:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13963281#comment-13963281
] 

Jean-Daniel Cryans commented on HBASE-10504:
--------------------------------------------

bq. It doesn't have to be 'our' RPC, right JD?

Right, I guess I meant RPC protocol instead of mechanism.

bq. You just have to write the znode data in the same format that hbase expects it to be in

You're right, so we just have to make it explicit. And also you need to be authenticated if
using security.

bq. The above statement makes it appear as though RPC protocol and zk serialization are more
brittle than they actually are.

Sorry, I was referring to the code that I had just linked to where they use our internal APIs
like ServerName and ZKUtil. Considering your two previous comments, that part of my writeup
is irrelevant.

> HBase has replication.  Fellas have been hijacking the replication apis to do all kinds
of perverse stuff like indexing hbase content (hbase-indexer https://github.com/NGDATA/hbase-indexer)
and our [~toffer] just showed up w/ overrides that replicate via an alternate channel (over
a secure thrift channel between dcs over on HBASE-9360).  This issue is about surfacing these
APIs as public with guarantees to downstreamers similar to those we have on our public client-facing
APIs (and so we don't break them for downstreamers).
> Any input [~phunt] or [~gabriel.reid] or [~toffer]?
> Thanks.
