Unnecessary snapshot transfers between new leader and followers ---------------------------------------------------------------
Key: ZOOKEEPER-876 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-876 Project: Zookeeper Issue Type: Bug Affects Versions: 3.3.1 Reporter: Diogo Priority: Minor When starting a new leadership, unnecessary snapshot transfers happen between new leader and followers. This is so because of multiple small bugs. 1) the comparison of zxids is done based on a new proposal, instead of the last logged zxid. (LearnerFollower.java:310) 2) if follower is one zxid behind, the check of the interval of committed logs excludes the follower. (LearnerFollower.java:269) 3) the bug reported in ZOOKEEPER-874 (commitLogs are empty after recover). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
