Class NettyRpcClientConfigHelper

java.lang.Object

org.apache.hadoop.hbase.ipc.NettyRpcClientConfigHelper

@InterfaceAudience.Public
public final class NettyRpcClientConfigHelper
extends Object

Helper class for passing config to NettyRpcClient.

As hadoop Configuration can not pass an Object directly, we need to find a way to pass the EventLoopGroup to AsyncRpcClient if we want to use a single EventLoopGroup for the whole process.

Since:

2.0.0
