Subject [jira] Commented: (ZOOKEEPER-202) Phantom ephemeral node
Date Tue, 21 Oct 2008 21:52:44 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-202?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641621#action_12641621

Flavio Paiva Junqueira commented on ZOOKEEPER-202:

Unfortunately, the leader logs were not available. We could perhaps take a look at the bugs
fixed on sourceforge then, to see if there is one that maps to this problem.

> One of our users has observed that an ephemeral znode had gone away once its creator
had disconnected according to the leader, but one follower believed that it existed long after
the znode had been deleted. Apparently the follower was never going to delete it. Because
the leader wouldn't recognize the znode as an existing one, any attempt to delete the znode
failed.  We have to investigate if this is related to any known bug, although, to my knowledge,
this is the first time it happens. It is important to note that the user was running an older
version of our code.
