No lockType configured for NRTCachingDirectory

[Markus Jelsma]

Hi,

Besides replication issues (see other thread) we're also seeing these warnings 
in the logs on all 10 nodes and for all cores using today's or yesterday's 
trunk.

2012-10-31 11:01:03,328 WARN [solr.core.CachingDirectoryFactory] - [main] - : 
No lockType configured for 
NRTCachingDirectory(org.apache.lucene.store.MMapDirectory@/opt/solr/cores/shard_h/data
 lockFactory=org.apache.lucene.store.NativeFSLockFactory@5dd183b7; 
maxCacheMB=48.0 maxMergeSizeMB=4.0) assuming 'simple'

The factory is configured like:

<config>
  <luceneMatchVersion>LUCENE_50</luceneMatchVersion>
  <directoryFactory name="DirectoryFactory" 
                    
class="${solr.directoryFactory:solr.NRTCachingDirectoryFactory}"/>

..
</config>

And the locking mechanisch is configured like:

<indexConfig>
..
<lockType>native</lockType>
..
</indexConfig>

Any ideas to why it doesn't seem to see my lockType? 

Thanks
Markus
