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
ERROR: java.lang.IllegalArgumentException: Not a host:port pair:
�12...@h-24-30.sfo.stumble.neth-24-30.sfo.stumble.net,60637,1320344107987
Backtrace: org/apache/hadoop/hbase/HServerAddress.java:60:in `<init>'
org/apache/hadoop/hbase/MasterAddressTracker.java:63:in
`getMasterAddress'
org/apache/hadoop/hbase/client/HConnectionManager.java:354:in
`getMaster'
org/apache/hadoop/hbase/client/HBaseAdmin.java:94:in `<init>'
{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:
�12...@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 version
