Subject [jira] [Commented] (HBASE-11467) New impl of Registry interface not using ZK + new RPCs on master protocol
Date Mon, 14 Jul 2014 23:24:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14061417#comment-14061417
] 

Mikhail Antonov commented on HBASE-11467:
-----------------------------------------

[~stack] that token management (which involves clusterId access) happens not at individual
protocol level  (i.e. MasterProtos), but at the rpc channel level (BlockingRpcChannelImplementation,
and RpcClient). So to do that, we would need to write new implementation of BlockingRpcChannel?

> 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.
> That includes adding several new methods to master RPC protocol:
> - GetMetaRegionLocation
> - GetClusterId
> - IsTableOnlineState
> - GetCurrentNrHRS
