> Key: OAK-7869
> URL: https://issues.apache.org/jira/browse/OAK-7869
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: documentmk
> Affects Versions: 1.0, 1.2, 1.4, 1.6.0, 1.8.0
> Reporter: Marcel Reutegger
> Assignee: Marcel Reutegger
> Priority: Major
> Fix For: 1.10

>
> This is the same scenario as described in OAK-7867 but for the
> DocumentNodeStore.
> The behaviour of the DocumentNodeStore is slightly different. The rogue
> InputStream will block the CommitQueue inside the DocumentNodeStore and
> prevent other commits from finishing. Other commits may proceed up to the
> point where changes are persisted, including the final update on the commit
> root document, but the merge calls for those commits will never return.
> It doesn't look like the issue can cause data loss, but can still affect
> availability of the system as other writes are blocked. Writes on other
> cluster nodes may also be affected because a blocked CommitQueue means
> already persisted commits are not propagated through the background update
> thread. Commits on other cluster nodes then may conflict because changes from
> the affected cluster node are not yet made visible.
