Duo Zhang commented on HBASE-27185:
-----------------------------------
Let's keep this for branch-2+ only, not for branch-2.5. Though I plan to do
this step by step, so in the current PR I do not change all the parse logic to
netty handler for NettyRpcServer, it still changes a lot of things and needs
more testing to confirm that there is no performance issue, and also no memory
leak.
> Rewrite NettyRpcServer to decode rpc request with netty handler

> Key: HBASE-27185
> URL: https://issues.apache.org/jira/browse/HBASE-27185
> Project: HBase
> Issue Type: Improvement
> Components: netty, rpc
> Reporter: Duo Zhang
> Priority: Major
>
> This is a follow on issue of HBASE-26708.
> The memory leaks happens in the saslReadAndProcess method. It does not follow
> a typical netty style so it is more likely to introduce bugs.
> Since we agree that NettyRpcServer is the future and SimpleRpcServer should
> be deprecated and finally removed, let's first implement dedicated rpc
> request decoder for netty.
