> Currently, multiple rpc servers are started in namenode, such as client rpc server, service rpc server, lifeline rpc server, and each rpc server used the same parameter 'ipc.server.read.threadpool.size' setting for the number of reader threads for this server .
> Consider according to different rpc server requirements set the number of reader threads for this server，for example:
> In client RPC server use parameter 'dfs.namenode.reader.count' ,
> In service RPC server use parameter 'dfs.namenode.service.reader.count' ,
> In lifeline RPC server use parameter 'dfs.namenode.lifeline.reader.count'
