Clint Morgan commented on HADOOP-4525:
--------------------------------------
I'm not gonna write a unit test just to make sure a config param is being read,
but maybe someone else wants to. (Making the field final helps a bit here)
I don't know how you say "it does not look like the this config is was ever
read by the server." It was at least being read in the patch that first
introduced it: HADOOP-2232
> config ipc.server.tcpnodelay is no loger being respected

> I was troubleshooting some slow IPC from hbase, and though it may be a
> Naggles algorithm issue. So I turned on tcpNoDelay on the client and server
> and this had no affect. Turns out that the "ipc.server.tcpnodelay" setting
> was no longer being read.
