Java replication replicates lucene lock file
--------------------------------------------

                 Key: SOLR-1170
                 URL: https://issues.apache.org/jira/browse/SOLR-1170
             Project: Solr
          Issue Type: Bug
          Components: replication (java)
    Affects Versions: 1.4
         Environment: linux
            Reporter: Bryan Talbot
            Priority: Minor


When using solr 1.4 replication, I see that the lucene-write.lock file is being 
replicated to slaves.  I'm importing data from a db every 5 minutes using cron 
to trigger a DIH delta-import.  Replication polls every 60 seconds and the 
master is configured to take a snapshot (replicateAfter) commit.

Why should the lock file be replicated to slaves?

The lock file isn't stale on the master and is absent unless the delta-import 
is in process.  I've not tried it yet, but with the lock file replicated, it 
seems like promotion of a slave to a master in a failure recovery scenario 
requires the manual removal of the lock file.
