Brian Nixon updated ZOOKEEPER-3056: ----------------------------------- Attachment: snapshot.0 > Fails to load database with missing snapshot file but valid transaction log > file > -------------------------------------------------------------------------------- > > Key: ZOOKEEPER-3056 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3056 > Project: ZooKeeper > Issue Type: Bug > Components: server > Affects Versions: 3.5.3, 3.5.4 > Reporter: Michael Han > Priority: Critical > Attachments: snapshot.0 > > > [An > issue|https://lists.apache.org/thread.html/cc17af6ef05d42318f74148f1a704f16934d1253f1472cccc1a93b4b@%3Cdev.zookeeper.apache.org%3E] > was reported when a user failed to upgrade from 3.4.10 to 3.5.4 with missing > snapshot file. > The code complains about missing snapshot file is > [here|https://github.com/apache/zookeeper/blob/release-3.5.4/src/java/main/org/apache/zookeeper/server/persistence/FileTxnSnapLog.java#L206] > which is introduced as part of ZOOKEEPER-2325. > With this check, ZK will not load the db without a snapshot file, even the > transaction log files are present and valid. This could be a problem for > restoring a ZK instance which does not have a snapshot file but have a sound > state (e.g. it crashes before being able to take the first snap shot with a > large snapCount parameter configured). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
