-------------------------------------
Summary: IndexCopier causes concurrent update on NodeBuilder
Key: OAK-5238
URL: https://issues.apache.org/jira/browse/OAK-5238
Project: Jackrabbit Oak
Issue Type: Bug
Components: lucene
Affects Versions: 1.4.0, 1.0.15, 1.2.3
Reporter: Marcel Reutegger
Fix For: 1.6
OAK-2247 introduced the copy-on-write feature for lucene index in Oak. This
feature may result in a NodeBuilder updated by multiple threads concurrently.
New index files are first stored on the local filesystem and then copied
asynchronously into the repository. At the same time the async index update
thread manipulates the node builders as well.
With MongoMK this results in unexpected conflicts and failed async index
updates.
