Otis Gospodnetic commented on SOLR-1853: ---------------------------------------- This issue is still open, but it looks like Paul fixed it 1 year ago? Shawn, is this still a problem for you? > ReplicationHandler reports incorrect replication failures > --------------------------------------------------------- > > Key: SOLR-1853 > URL: https://issues.apache.org/jira/browse/SOLR-1853 > Project: Solr > Issue Type: Bug > Components: replication (java) > Affects Versions: 1.4 > Environment: Linux > Reporter: Shawn Smith > > The ReplicationHandler "details" command reports that replication failed when > it didn't. This occurs after a slave is restarted when it is already in sync > with the master. This makes it difficult to write production monitors that > check the health of master-slave replication (no network issues, unexpected > slowdowns, etc). > From the code, it looks like "SnapPuller.successfulInstall" starts out false > on restart. If the slave starts out in sync with the master, then each no-op > replication poll leaves "successfulInstall" set to false which makes > SnapPuller.logReplicationTimeAndConfFiles log the poll as a failure. > SnapPuller.successfulInstall stays false until the first time replication > actually has to do something, at which point it gets set to true, and then > everything is OK. > h4. Steps to reproduce > # Setup Solr master and slave servers using Solr 1.4 Java replication. > # Index some content on the master. Wait for it to replicate through to the > slave so the master and slave are in sync. > # Stop the slave server. > # Restart the slave server. > # Wait for the first slave replication poll. > # Query the replication status using > "http://localhost:8983/solr/replication?command=details" > # Until the master index changes and there's something to replicate, all > slave replication polls after the restart will be shown as failed in the XML > response. -- This message is automatically generated by JIRA.
