Subject [jira] Commented: (SOLR-1395) Integrate Katta
Date Mon, 29 Nov 2010 11:51:46 GMT


JohnWu commented on SOLR-1395:


         oh, Thanks!
         for this patch, we overcome some obstacles and share with everyone focus on this
         1) if you want debug the program with katta code, please do not use the katta code
from SVN, which lib is so old (lucene is 2.4, hadoop is 0.19, zookeeper is 3.1.1), you need
use Git trunk the code and build a eclipse project.
         2) build a WTP project with the TomLiu patched solr in eclipse, and reference above
katta project.
         3) copy the of katta project to solr project lib (It's so terrible,
the exception report less IOItech, that means 101tech)

debug run!

       Can you tell me the conf of solrHome?
       we want to know the solr core deploy in build the proxy process?(if that, the process
likes the 1301 patch) or the solr core already exists there, waiting for query?
