Flavio Junqueira commented on ZOOKEEPER-1639:
---------------------------------------------
I'm missing some context here. What kind of incorrect behavior does this bug
induces?
> zk.getZKDatabase().deserializeSnapshot adds new system znodes instead of
> replacing existing ones
> ------------------------------------------------------------------------------------------------
>
> Key: ZOOKEEPER-1639
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1639
> Project: ZooKeeper
> Issue Type: Bug
> Affects Versions: 3.4.5
> Reporter: Alexander Shraer
>
> Before the call to zk.getZKDatabase().deserializeSnapshot in Learner.java,
> zk.getZKDatabase().getDataTree().getNode("/zookeeper") ==
> zk.getZKDatabase().getDataTree().procDataNode, which means that this is the
> same znode, as it should be.
> However, after this call, they are not equal. The node actually being used in
> client operations is zk.getZKDatabase().getDataTree().getNode("/zookeeper"),
> but the other old node procDataNode is still there and not replaced (in fact
> it is a final field).
