Amit Nithian updated SOLR-4471:
-------------------------------
Attachment: SOLR-4471.patch
I have a proposed solution with a bit of extra commentary on it in the code so it's clear what I am doing.

> Key: SOLR-4471
> URL: https://issues.apache.org/jira/browse/SOLR-4471
> Project: Solr
> Issue Type: Bug
> Components: replication (java)
> Affects Versions: 4.1
> Reporter: Andre Charton
> Labels: master, replication, slave, version
> Attachments: SOLR-4471.patch
>
>
> Scenario: master/slave replication, master delta index runs every 10 minutes, slave poll interval is 10 sec.
> There was an issue SOLR-4413 - slave reads index from wrong directory, so slave is full copy index from master every time, which is fixed after applying this patch from 4413 (see script below).
> Now on replication the slave downloads only updated files, but slave is create a new segement file and also a new version of index (generation is identical with master). On next polling the slave is download the full index again, because the new version slave is force a full copy.
> Problem is the new version of index on the slave after first replication.
> {noformat:apply patch SOLR-4413 script, please copy patch into patches directory before useage.}
> mkdir work
> cd work
> svn co http://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_4_1/
> cd lucene_solr_4_1
> patch -p0 < ../../patches/SOLR-4413.patch
> cd solr
> ant dist
> {noformat}
