Raul Gutierrez Segales commented on ZOOKEEPER-1732:
---------------------------------------------------
What's wrong with the round values? i.e.: the two new servers have IGNOREVALUE
(sounds correct right?) and the older followers have the current round value
(i.e.: 0x6). I thought the problem would be here:
{noformat}
* @see
https://issues.apache.org/jira/browse/ZOOKEEPER-1732
*/
outofelection.put(n.sid, new Vote(n.leader,
IGNOREVALUE, IGNOREVALUE, n.peerEpoch,
n.state));
if (termPredicate(outofelection, new Vote(n.leader,
IGNOREVALUE, IGNOREVALUE, n.peerEpoch, n.state))
&& checkLeader(outofelection, n.leader,
IGNOREVALUE)) {
{noformat}
IGNOREVALUE doesn't work here, because we are talking to un-patched cluster
members.
Sorry if I am completely misleading you :) That's as far as I got with my
analysis today.

> I have a test in which I do a rolling restart of three ZooKeeper servers and
> it was failing from time to time.
> I ran the tests in a loop until the failure came out and it seems that at
> some point one of the servers is unable to join the enssemble formed by the
> other two.
