[jira] [Updated] (OAK-2029) Oak Lucene index doesn't get notified about updates when index is stored on the file system

["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/OAK-2029?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chetan Mehrotra updated OAK-2029:
---------------------------------

    Attachment: OAK-2029.patch

Patch with testcase and fix

{{LuceneIndexEditorContext}} would also record some stats in ":status" child node of index definition node. For example
* /oak:index/lucene/:status/lastUpdated - Records time of last update
* /oak:index/lucene/:status/indexedNodes -Number of nodes indexed

With this the IndexNode would detect change in index node and would reopen the Directory

[~alexparvulescu] Can you review the patch?

> It looks like the the lucene IndexTracked class responsible for refreshing the in-memory cache of the lucene index doesn't get the update notification when the index is stored on the file system.
> This results in searches not working until the next restart
