Roland Deck created SOLR-4100:
---------------------------------
Summary: 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}

3) 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_DUE");
doc.addField("title", "some test title for due");
UpdateResponse urep = solrServer.add(doc, 10000); //commit within 10s.
System.out.println("response status: "+urep.getStatus());
}
This works on the master, but the version number is left the same, so that
replication doesn't take place, leaving the slave in the previous state.
This is certainly a bug and should be fixed.
The logfile states as following:
INFO: [eventlocation] webapp=/solr path=/update params={wt=javabin&version=2}
{add=[TEST_ID_DUE]} 0 249
INFO: start
commit{flags=0,_version_=0,optimize=false,openSearcher=true,waitSearcher=true,expungeDeletes=false,softCommit=true}

INFO: Opening Searcher@18590c5 main
21.11.2012 08:37:30 org.apache.solr.update.DirectUpdateHandler2 commit
INFO: end_commit_flush
It seams to me that this softCommit mechanism doesn't work properly yet.
