[jira] Updated: (LUCENE-2856) Create IndexWriter event listener, specifically for merges

     [ https://issues.apache.org/jira/browse/LUCENE-2856?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Rutherglen updated LUCENE-2856:
-------------------------------------

    Attachment: LUCENE-2856.patch

I added a SegmentListener class which is set on IWC.  I still need to write unit tests and add an event for aborted merges.

Perhaps we want to enable a collection of segment listeners instead of only one?

> The issue will allow users to monitor merges occurring within IndexWriter using a callback notifier event listener.  This can be used by external applications such as Solr to monitor large segment merges.
