Alexander Shraer commented on ZOOKEEPER-1270:
---------------------------------------------
Hi Flavio,
LearnerHandler sends NEWLEADER messages after running waitForEpochAck.
The patch makes sure that waitForEpochAck does not return until the leader also
runs it. Leader runs waitForEpochAck after inserting NEWLEADER message into the
outstandingProposals.
