Duo Zhang updated HBASE-18307:
------------------------------
Attachment: HBASE-18307.patch
Create a NettyEventLoopGroupConfig for HRegionServer, and in NettyRpcServer it
will get it from the Server instance passed in. Server is marked as
IA.LimitedPrivate so I do not want to add the method to it as the method will
leak the netty things out.
And for AsyncFSWAL, it is in another package and is not bound to a RS, so use
the same way with NettyRpcClient to pass the EventLoopGroup to it.
Yeah it is possible that user modifies the default configs and refuses to use
any netty related implementations and makes the EventLoopGroup stored in
HRegionServer useless. But I think for performance it is OK? The threadx will
be blocked on fetching tasks and not consume any CPUs.
Thanks.
