Thawan Kooburat commented on ZOOKEEPER-1790: -------------------------------------------- In our internal deployment, we use negative sid to for observers (actually all of them is -1) . This is probably not the intended usage but it worked so far. It would be nice to add to release note of 3.5 if there is a change in the valid sid range. > Deal with special ObserverId in QuorumCnxManager.receiveConnection > ------------------------------------------------------------------ > > Key: ZOOKEEPER-1790 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1790 > 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) -- This message was sent by Atlassian JIRA (v6.1#6144)
