> A 3-node cluster is on version 0.8.9, 1.0.6, or 1.0.7 and then one and only one node is taken down, upgraded to trunk, and started again. An rpc timeout exception happens if counter-add operations are done. It usually takes between 1 and 500 add operations before the failure occurs. The failure seems to happen sooner if the coordinator node is NOT the one that was upgraded. Here is the error: 
> {code}
> ======================================================================
> ERROR: counter_upgrade_test.TestCounterUpgrade.counter_upgrade_test
> ----------------------------------------------------------------------
> Traceback (most recent call last):
>   File "/usr/lib/pymodules/python2.7/nose/case.py", line 187, in runTest
>     self.test(*self.arg)
>   File "/home/tahooie/cassandra-dtest/counter_upgrade_test.py", line 50, in counter_upgrade_test
>     cursor.execute("UPDATE counters SET row = row+1 where key='a'")
>   File "/usr/local/lib/python2.7/dist-packages/cql/cursor.py", line 96, in execute
>     raise cql.OperationalError("Request did not complete within rpc_timeout.")
> OperationalError: Request did not complete within rpc_timeout.
> {code}
> A script has been added to cassandra-dtest (counter_upgrade_test.py) to demonstrate the failure. The newest version of CCM is required to run the test. It is available here if it hasn't yet been pulled: git@github.com:tpatterson/ccm.git
