Subject [jira] [Commented] (SOLR-8837) Duplicate leader elector node detection is broken
Date Mon, 21 Mar 2016 15:53:25 GMT


Alan Woodward commented on SOLR-8837:

Thanks Scott, I'll commit this fix.  Looks like the bug crept in with SOLR-8697, so it hasn't
actually been released.

> LeaderElector.checkIfIAmLeader checks to see if it has duplicate registrations in under
its election node, but it does this by prefix checking, which means that if core_node1 registers
itself after core_node11, it will think it's a duplicate, and delete the core_node11 node.
