stack commented on HBASE-3939:
------------------------------

We can't get to the new rpc message because 0.90.x clients don't get that far; they fail reading
zookeeper master entry:

{code}
hbase(main):002:0> debug
Debug mode is ON

hbase(main):003:0> list 
TABLE

{code}

ServerName is in the way of our getting to rpc.

I tried making an HBaseAdmin instance but that don't work because on construction it tries
to talk to Master (which is dumb):

{code}
hbase(main):008:0> a = HBaseAdmin.new(c)
NativeException: java.lang.IllegalArgumentException: Not a host:port pair: �12054@h-24-30.sfo.stumble.neth-24-30.sfo.stumble.net,60637,1320344107987
{code}

Can't create an HTable.

Reverting the ServerName change is not an option.

> A few fixes from Hadoop IPC that we should probably cross-port into our copy:
> - HADOOP-7227: remove the protocol version check at call time
> - HADOOP-7146: fix a socket leak in server
> - HADOOP-7121: fix behavior when response serialization throws an exception
> - HADOOP-7346: send back nicer error response when client is using an out of date IPC
