Patrick Hunt commented on ZOOKEEPER-335:

Side note: Flavio can you enter a JIRA to fix this log message, it would really 
be helpful to have attribute names in the log message do simplify debugging. 
(general review of quorum logging would be great, fix stuff like this and 
ensure that enough information is provided to debug - add logging?) Perhaps 
coordinate with Ivan, I think he was trying to change things a bit to enable 
more log analysis support in the "loggrapher" contrib.

> currently the zookeeper followers do not commit the new leader election. This 
> will cause problems in a failure scenarios with a follower acking to the same 
> leader txn id twice, which might be two different intermittent leaders and 
> allowing them to propose two different txn's of the same zxid.
