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

TomLiu:

        I still jam in the query dipatch  to subproxy!

SEVERE: Error calling public abstract org.apache.solr.katta.KattaResponse org.apache.solr.katta.ISolrServer.request(java.lang.String[],org.apache.solr.katta.KattaRequest)
throws java.lang.Exception on pc-slave02:20000 (try # 1 of 3) (id=0)
java.lang.reflect.InvocationTargetException

       so, I give you my config in proxy, please review them:

       in proxy 

           1)
            solrHome-> solrconfig.xml
                     <config>

                             <requestHandler name="standard" class="solr.KattaRequestHandler"
default="true">

                            <lst name="defaults">
                            <str name="echoParams">explicit</str>
                            <str name="shards">*</str>
                            </lst>
                           </requestHandler>
                    </config>

                  ok, all the shard is watched and hold in Zookeeper, through zookeeper zkCli.sh

                 [zk: pc-master(CONNECTED) 11] ls /katta/shard-to-nodes
                 [SPIndex05#1287138886138-99384445, SPIndex04#1287138886138-99384445]

                2)
                 In proxy 
                 katta.node.properties:
                 node.server.class=net.sf.katta.lib.lucene.LuceneServer


               3)
                query:  http://localhost:8080/solr-1395-katta-0.6.2-2patch/select/?q=lovealice&version=2.2&start=0&rows=10&indent=on&isShard=false&distrib=true
                
                is that right?
               especial in this step 2,

Thanks!

JohnWu
