How do we tell the slaves to point to the new master without modifying the config files? Can we do this while the slave is up, issuing a command to it? Thanks, Tri

Solr doesn't support automatic failover of the master, at least in 1.4.1. I've been discussing with my colleague (Tommaso) about ways to achieve this. There's ways we could 'fake it', scripting the following: * set up a 'backup' master, as a replica of the actual master * monitor the master for 'up-ness' * if it fails: * tell the master to start indexing to the backup instead * tell the slave(s) to connect to a different master (the backup) * then, when the master is back: * wipe its index (backing up dir first?) * configure it to be a backup of the new master * make it pull a fresh index over But, Jan Høydahl suggested using SolrCloud. I'm going to follow up on how that might work in that thread.
