Camille Fournier commented on ZOOKEEPER-1270:
---------------------------------------------
You have come to the same conclusion I did. The leader sends snapshots to the
followers and they both log that they are taking a snaphsot (implying that we
got the NEWLEADER message), but you don't see anything in the log that
indicates the leader actually managed to call processAck on either of the
responses, where you should see something like:
2011-11-03 13:07:49,717 [myid:2] - WARN
[LearnerHandler-/127.0.0.1:63083:Leader@506] - Commiting zxid 0x200000000 from
/127.0.0.1:11228 not first!
2011-11-03 13:07:49,717 [myid:2] - WARN
[LearnerHandler-/127.0.0.1:63083:Leader@508] - First is 0
Not sure why yet though.
