--------------------------------------------------------------
Would it make sense for using
[OAK_VERSION_KEY|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/document/ClusterNodeInfo.java#L60]
to see it's pre-1.3.7 and not worry about that entry in that case?
I feeling missing (not observing) a single WARN for a legitimate issue is easy
- as it'd come during startup and there are way too many logs at the time to
notice.

> Issue Type: Bug

> With DocumentDiscoveryLiteService in 1.3.7 the following WARN has been
> noticed:
> {code}
> 07.10.2015 06:38:16.575 *TRACE*
> [DocumentDiscoveryLiteService-BackgroundWorker-[4]]
> org.apache.jackrabbit.oak.plugins.document.DocumentDiscoveryLiteService
> hasBacklog: start. clusterNodeId: 1
> 07.10.2015 06:38:16.575 *TRACE*
> [DocumentDiscoveryLiteService-BackgroundWorker-[4]]
> org.apache.jackrabbit.oak.plugins.document.DocumentDiscoveryLiteService
> getLastKnownRevision: end. clusterNode:
> 1, lastKnownRevision: r14e0c0898cc-0-1
> 07.10.2015 06:38:16.575 *WARN*
> [DocumentDiscoveryLiteService-BackgroundWorker-[4]]
> org.apache.jackrabbit.oak.plugins.document.DocumentDiscoveryLiteService
> hasBacklog: node has lastWrittenRootRev=
> null
> {code}
> This happens every 5sec. While the warning is somewhat legitimate as it
> cannot determine the backlog of a not-active instance - it is spam if it
> occurs every 5sec. So rather than warning constantly, there should only be
> one warning and then a fall-back to log.debug afterwards.
