Thanks for this. I've updated trunk/, rebuilt solr.war, however, running into another issue.

Sep 27, 2009 1:55:44 PM org.apache.solr.common.SolrException log

Also, the log file has a bunch of these lines:

Sep 27, 2009 1:55:56 PM org.apache.solr.update.SolrIndexWriter finalize
SEVERE: SolrIndexWriter was not closed prior to finalize(), indicates a bug -- POSSIBLE RESOURCE LEAK!!!


Here is the snippet from my solrconfig.xml


  <indexDefaults>
<!-- Values here affect all index writers and act as a default unless overridden. -->
    <useCompoundFile>false</useCompoundFile>

    <mergeFactor>6</mergeFactor>
    <ramBufferSizeMB>500</ramBufferSizeMB>
    <maxFieldLength>10000</maxFieldLength>
    <writeLockTimeout>1000</writeLockTimeout>
    <commitLockTimeout>10000</commitLockTimeout>
<mergePolicy class="org.apache.lucene.index.LogByteSizeMergePolicy">
      <boolean name="calibrateSizeByDeletes">true</boolean>
    </mergePolicy>
<mergeScheduler>org.apache.lucene.index.ConcurrentMergeScheduler</ mergeScheduler>
    <lockType>single</lockType>
  </indexDefaults>




Thanks,

Hello,

It looks like solr is not allowing me to change the default
MergePolicy/Scheduler classes.

Even if I change the default MergePolicy/ Scheduler(LogByteSizeMErgePolicy and ConcurrentMergeScheduler) defined in solrconfig.xml to a different one (LogDocMergePolicy and SerialMergeScheduler), my profiler shows the default
classes are still being loaded.

Also, if I use the default LogByteSizeMergePolicy, I can't seem to
override the 'calibrateSizeByDeletes' to 'true' value using solrconfig using
the new syntax that was introduced this week (SOLR-1447).

I'm using the version checked out from trunk yesterday.

Any pointers will be helpful.


Specifying mergePolicy and mergeScheduler in <indexDefaults> does not work in trunk. If you specify in the <mainIndex> section, it will work. I'll give
a patch with a fix.


This is fixed in trunk now. Thanks!
