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.
