Subject [jira] [Commented] (ZOOKEEPER-1790) Deal with special ObserverId in QuorumCnxManager.receiveConnection
Date Sat, 02 Nov 2013 02:47:18 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-1790?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13811852#comment-13811852

Raul Gutierrez Segales commented on ZOOKEEPER-1790:
---------------------------------------------------

[~fpj]: I don't think it's related - my initial assessment was wrong. It isn't connection
attempts that generate the extra traffic I am seeing but the Notifications (as commented in
ZOOKEEPER-1807).

>             Project: ZooKeeper
>          Issue Type: Bug
>          Components: server
>    Affects Versions: 3.4.6, 3.5.0
>            Reporter: Alexander Shraer
>            Assignee: Alexander Shraer
>             Fix For: 3.4.6, 3.5.0

> QuorumCnxManager.receiveConnection assumes that a negative sid means that this is a 3.5.0
server, which has a different communication protocol. This doesn't account for the fact that
ObserverId = -1 is a special id that may be used by observers and is also negative. 
> This requires a fix to trunk and a separate fix to 3.4 branch, where this function is
different (see ZOOKEEPER-1633)
