stack commented on HBASE-8804:
------------------------------
[~jmspaggi] That looks like old client trying to read znode written by new
client or, is that garbage after the ServerName:
{code}
java.lang.IllegalArgumentException: Not a host:port pair:
de7,60020,1370440536028
X��UIntegrationTestBigLinkedListm�N�|�,1366851785897.6fb3d84e41ffed2f
{code}
... the IntegrationTestBigLinkedListm... stuff? That would be interesting if
we included that in a ServerName.
