Subject [jira] Commented: (SOLR-1395) Integrate Katta
Date Thu, 02 Dec 2010 09:48:20 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1395?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12966040#action_12966040

tom liu commented on SOLR-1395:
-------------------------------

solrHome is set :
# webapps/yourapp/web.xml
this is conf of frontserver or proxy.
# katta script
this is conf of subproxy. such as:
{noformat}
...
KATTA_OPTS="$KATTA_OPTS -Dsolr.home=/var/data/solr/kattaproxy"
...
{noformat}
# solrcore
this conf would be set by Katta/Solr automatic.

in katta integration, tomcat (or jetty) is the trigger point, which connected to zkserver
and katta nodes.
katta nodes that deployed solrcores are waiting for querys from tomcat.
