----------------------------------------------
[~Damon], you seem to have created four separate JIRA issues for the same
thing. Please limit yourself to one JIRA per issue. You can edit this issue
(ZOOKEEPER-4253) if you need to make changes. You do not need to create any
more issues. I have marked the others as duplicates of this one.
> I connected to ZooKeeper at different times, but I got the same session ID
> --------------------------------------------------------------------------
>
> Key: ZOOKEEPER-4253
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4253
> Project: ZooKeeper
> Issue Type: Bug
> Components: java client
> Affects Versions: 3.4.13
> Reporter: Damon Liu
> Priority: Major
> Attachments: zookeeper.log
>
>
> I have an app AA connect to zookeeper and register a temporary path such as
> /brokers/ids/10，and I have another app BB also connect to zookeeper. At some
> point, AA BB and ZooKeeper both restarted
> before restart:
> AA connect log in zk : [2021-03-07 08:47:43,468] INFO [SyncThread:0]
> Established session {color:#FF0000}0x10000053ef90000{color} with negotiated
> timeout 8000 for client /{color:#FF0000}22.20.0.45{color}:59966
> (org.apache.zookeeper.server.ZooKeeperServer)
> after restart:
> BB connect log in zk:[2021-03-07 08:58:51,351] INFO [SyncThread:0]
> Established session {color:#FF0000}0x10000053ef90000{color} with negotiated
> timeout 30000 for client /{color:#FF0000}22.20.0.47{color}:39360
> (org.apache.zookeeper.server.ZooKeeperServer)
>
> I understand that when ZooKeeper restarts, the transaction log and snapshot
> files will be loaded, and the old
> session({color:#FF0000}0x10000053EF90000{color}) and the temporary path will
> be loaded,If App BB gets the old session
> {color:#FF0000}0x10000053EF90000{color}, the session will not expire, the
> temporary path（/brokers/ids/10） will not be deleted, and App AA will not be
> able to re-register the temporary path(/brokers/ids/10)。
> That's my question，looking forward to your help. Thank you.
