I found some more information. Here's how Thrift tries to connect to zookeeper:
2010-10-08 17:18:37,049 INFO org.apache.zookeeper.ClientCnxn: Socket connection established to localhost/fe80:0:0:0:0:0:0:1%1:2181, initiating session 2010-10-08 17:18:37,064 INFO org.apache.zookeeper.ClientCnxn: Session establishment complete on server localhost/fe80:0:0:0:0:0:0:1%1:2181, sessionid = 0x12b8e5a7b240002, negotiated timeout = 60000 For one thing, the client never gets a response from the server. For another thing, Thrift is using ipv6 for some reason. Very confused.
