Yonik Seeley commented on SOLR-4100:
------------------------------------
bq. Is this behavior wished or a bug?
It's by design for commitWithin to be soft by default - the idea was that most
people were using commitWithin only to make their documents visible to search,
not to trigger replication.
> commitWithin (soft commit = true): version number of master index not changed
> => no replication to slave is done!

> Key: SOLR-4100
> URL: https://issues.apache.org/jira/browse/SOLR-4100
> Project: Solr
> Issue Type: Bug
> Components: replication (java)
> Affects Versions: 4.0
> Reporter: Roland Deck

> I have a master and a slave solr instance. In solrconfig.xml, a replication
> handler is present (slave points to master via masterUrl).
> 1) If you add a document to the master solr via curl http:// ....: This works
> and the document is replicated to the slave.
> 2) If you add a document in Java via solrj and use the following code snippet:
> public static void main(String[] args) throws Exception {
> ConcurrentUpdateSolrServer solrServer =
> SolrServerFactory.createSolrServerForUpdate("localhost", "9100",
> "/solr", "eventlocation", 5, 2);
> SolrInputDocument doc = new SolrInputDocument();
> doc.addField("id", "TEST_ID");
> doc.addField("title", "some test title");
> UpdateResponse urep = solrServer.add(doc);
> System.out.println("response status: "+urep.getStatus());
> solrServer.commit();
> }
>
> This works and the document is replicated to the slave.
> The logfile states as following:
> INFO: [eventlocation] webapp=/solr path=/update params={wt=javabin&version=2}

> This works on the master, but the version number is left the same, so that
