Dan Milon updated ZOOKEEPER-2960: --------------------------------- Description: After upgrading from zookeeper 3.4.5, to 3.4.11, without editing {{zoo.cfg}}, the new version of the server tries to use the {{dataDir}} as the {{dataLogDir}}, and the {{dataLogDir}} as the {{dataDir}}. Or at least some parts of the server. Configuration file has: {noformat} $ grep -i data /etc/zookeeper/zoo.cfg dataLogDir=/var/lib/zookeeper/datalog dataDir=/var/lib/zookeeper/data {noformat} But runtime configuration has: {noformat} $ echo conf | nc localhost 2181 | grep -i data dataDir=/var/lib/zookeeper/datalog/version-2 dataLogDir=/var/lib/zookeeper/data/version-2 {noformat} Also, I got this in the debug logs, so clearly some parts of the server confuse things. {noformat} [PurgeTask:FileTxnSnapLog@79] - Opening datadir:/var/lib/zookeeper/datalog snapDir:/var/lib/zookeeper/data [main:FileTxnSnapLog@79] - Opening datadir:/var/lib/zookeeper/data snapDir:/var/lib/zookeeper/datalog {noformat} I tried to look in the code for wrong uses of the directories. I only found [ZookeeperServer.java|https://github.com/apache/zookeeper/blob/master/src/java/main/org/apache/zookeeper/server/ZooKeeperServer.java#L227] is passing the arguments to {{FileTxnSnapLog}} in the wrong order, but the code comment says that this is legacy only for tests, so I assume it isn't the cause for my case. was: After upgrading from zookeeper 3.4.5, to 3.4.11, without editing {{zoo.cfg}}, the new version of the server tries to use the {{dataDir}} as the {{dataLogDir}}, and the {{dataLogDir}} as the {{dataDir}}.
