Github user lvfangmin commented on the issue: https://github.com/apache/zookeeper/pull/605 @anmolnar the conflict is due to the missing of FuzzySnapshotRelatedTest class introduced in ZOOKEEPER-3127, which is fixing the data inconsistency due to multi-op txn. We need that in 3.5 as well, if you cherry pick that to 3.5 first, then we won't have conflict for this one. Manually tested cherry pick ZOOKEEPER-3127 to 3.5 branch, there is a very minor conflict in QuorumPeerMainTest, it should be trivial to change while cherry-picking.
