Subject [jira] [Commented] (HBASE-16584) Backport the new ipc implementation in HBASE-16432 to branch-1
Date Tue, 07 Mar 2017 02:34:33 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16584?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15898629#comment-15898629

Duo Zhang commented on HBASE-16584:
-----------------------------------

Let me pick this up. We decide to upgrade to HBase-1.x late this year and we want to use async
client as our internal code base is jdk8 only. So if master and branch-1 can share the same
rpc implementation, it is much easier for us to backport the async client stuffs to branch-1
in our internal version.

> Two problems.
> First, as RpcCliemtImpl is the default implementation on branch-1, we need to confirm
that the modification on master does not make it slower. I'm not sure but I used a big lock
to protect everything in the new implementation, so it may have bad impact on performance.
> Second, some configurations of the old AsyncRpcClient is gone. Such as "hbase.rpc.client.threads.max"
and "hbase.rpc.client.nativetransport". Now You could pass a EventLoopGroup object directly
through a helper class which makes it more flexible.
