JohnWu commented on SOLR-1395:
------------------------------

Tomliu:
   Do you mean ISolrServer use katta script to direct the query core home and indexDirectory?
   
   now I use a katta with solr patched jar to start the subproxy, the solr home is set in katta script:
   
   -Dsolr.home=/home/hadoop/workspace/kattaNoZK/solrHome

   in conf folder of solrHome the solrconfig.xml is:

   <requestHandler name="standard" class="solr.SearchHandler" default="true">
    <!-- default values for query parameters -->
     <lst name="defaults">
       <str name="echoParams">explicit</str>
       <!--<str name="shards.qt">tvrh</str>  --> 
     </lst>
   </requestHandler>
   
   so the solr send the query to this core of solrHome with searchHanler (which use query component and return the Doclice)

As you yesterday said, I need correct the solrHome of katta script (slave node) direct it to query core? but how to configure the sub-proxy solr home with solr.searchHandler?

Thanks!

JohnWu
