Subject [jira] Commented: (SOLR-1395) Integrate Katta
Date Thu, 02 Dec 2010 12:44:20 GMT


JohnWu commented on SOLR-1395:

         yeah, today I use the katta Git code (Maybe katta0.6.3) add the lib: solr-1395-katta-0.6.2-3patch.jar
        bin/katta startNode org.apache.solr.katta.DeployableSolrKattaServer

but back the error as follows:

       INFO: Solr home set to '/home/hadoop/workspace/kattaNoZK/solrHome/'
       ERROR: could not create instance of class 'org.apache.solr.katta.DeployableSolrKattaServer':
defaultCore:proxy could not be found

I ask an question:
       DeployableSolrKattaServer is for dispatch kattaRequest to subproxy, is right? which
will use the in 
        T result = (T) _method.invoke(proxy, _args); to reflect kattaRequests to nodes?

in proxy, Myquery is :
       is that right?

Thank you for your patience to answer me.

today, I receive a email form aladeck, he let me introduce the whole process step by step,
but I meet so many problem, I recommend you to answer this question for him.

If you are so busy, please help gets some key advices to me, I would first send an report
to you, your reviewed, then I send it to them.
