Subject [jira] [Commented] (LUCENE-3493) Solr reopen on a custom reader doesn't work
Date Thu, 06 Oct 2011 16:23:29 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3493?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13122050#comment-13122050

Jason Rutherglen commented on LUCENE-3493:
------------------------------------------

bq. Solr's NRT does not rely on a custom IndexReader

Yikes, logically the custom reader functionality should!

{quote}properly override doOpenIfChanged, else it would be a bug{quote}

It's a bug because there's no way to implement that today.  The DirectoryReader is created
deep inside of IW.getReader (there's no way to re-implement it's functionality either because
of private variable access).  

I think we need a protected method for creating reader in IW.  I think though this becomes
almost endless because I don't think there's a way to implement a custom IW in Solr.

> When a custom index reader is used with Solr and reopen, the custom reader vanishes after
the reopen.  It's a bug.
