> LogSegmentMetadataStore should only notify when the list of log segments is
> updated

> Key: DL-93
> URL: https://issues.apache.org/jira/browse/DL-93
> Project: DistributedLog
> Issue Type: Improvement
> Components: distributedlog-core
> Reporter: Sijie Guo
> Assignee: Sijie Guo
> Fix For: 0.4.0
>
>
> Currently it notifies the listeners not only when there is a change but also
> when session expires. it would break the reada
> head loop and cause readers have to wait until it is able to connect to
> zookeeper again.
> With this change, it would only notify when the list of log segments is
> updated. If it disconnects to zookeeper, the listen
> er won't be notified and it would keep reading from the log segments it knows.
