[jira] [Updated] (ZOOKEEPER-2960) The dataDir and dataLogDir are
used opposingly
[ https://issues.apache.org/jira/browse/ZOOKEEPER-2960?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
maoling updated ZOOKEEPER-2960:
-------------------------------
Description:
_emphasized text_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.
